I talk about the promax small block Ford 185 cc cylinder head and show the flow numbers.  Website: www.wengines.com Email: weingartnerracing@gmail.com
Hey Eric, Tim here, WOW!!..for 185cc's its pretty snazy!!!...if it was goin on MY SBF, i'd do a back cut on the intakes, as at 185 cc's, its NOT gonna be a screamer, NOR shud it be on a Windsor motor, but an intake back cut wud give MORE usable flow down low, where this head wud mostly live......impressive head tho......this comin from a Pontiac guy......i was impressed!!..TY sir!!
Wonder why the flow numbers are lower than what Promaxx advertises on their website. I'd love to see how the new LMR SVE CNC 185s stack up against these guys. Thanks for making this video!
Guess who forgot the thread sealant on the rocker studs, that’s one benefit of buying the heads from you. I can go back and watch the video on them. Just got them out on last week and it’s been smoking at idle and shifts. I’m here banging my head against the wall cause it wasn’t smoking before. Heck I thought I done hurt something, then I remembered, I didn’t put threads sealant on the studs, and bet they need it. Well off to go pull the intake rockers off, lol. At least that’s all it is I think! Thanks again Eric. Car is running pretty dang good, need to lean out the carb and I think it’s going pretty quick little car.
Hello ERIC That engine at the beginning of the run seemed to be very unhappy, or the dyno was having trouble. When engines start a run AND are not happy it Carrie’s on through the rpm range, There are a couple of things to try. Start the test at a higher rpm Try A faster acceleration test Static tests at peak Torque and HP When doing the statics hold it under load observing if it stays stable gains or loses. The accuracy of the dyno from run to run is at best 1/2 to 1 % The software also has dampening also called other names. This cuts out highs n lows giving better looking Graphs. I find your observations on the vein very interesting. You touched on reversion I would also point out that there are pulses that occur in the intake n exhaust Pro stock uses the first pulse, dirt track engines around the third pulse What we chase is inertia supercharge affect I am chucking this out there If the vein creates a swirl or vortex behind the valve on closing would this dampen the pulse and therefore lose power I am not a fan of that chamber style, may flow a little better always found they didn’t run well at low rpm I have been using Superflow dynos since 1983. My mentor there was the late Harold Bette’s
Another great video! Have they achieved these flow figures with ports bigger than the advertised 185cc? Or bigger cross sectional area at least.. Obviously port volume isn't the full story.. I feel like I would want to fit 8mm valves to a set of these as per the AFR hardware.
So .600 lift cam, back cut intake and tulip exhaust would work very well wirh these heads on a 10.5:1 306?! Very weird you just uploaded this as I rewatched the 210 video earlier and was just looking at these heads 😂
Can’t wait to put these on. Scored a 650xp couple nights ago, with the victor jr I picked up, should be pretty fun little engine, with the 5 speed. Briefly we talked about rockers, was wondering what brand you’d recommend? Was thinking about trick flow ones in 1.6 ratio.
Eric, Excellent content! This is what I've been waiting for!...Can you please take a measurement as to how much this head can be surfaced for compression? I really need to know your professional opinion...Thanks much, keep up the great work....
is that exhaust bolt patter then same as World products windsor Jrs? because i know headman headers makes headers for my fox but its only for that windsor jr pattern,. this looks like the same one??? and AFR does it??
just out of curiosity, is it possible to port and fill the exhaust port so its essentially a raised port? would there be enough meat on the port ceiling to allow that?
guideplates for big pushrods available? I'm going to build two 351W one for a Bronco and one for a LTD stock efi (302 top on the LTD) these look like good heads with around 500 lift HR cams The stock heads are going to need a lot of work so thinking
January 2025.... I just left your website and it only lists RHS, BRODIX and DART heads for a SBF. I didn't see any Promaxx heads listed under the LS category either. Do you not offer the Promaxx heads any longer? Thanks.
Interestly, I ported a set of DRP 185s which appear to the same castings. They are actually 205cc when measured and flowed sub 240. Cleaned them up and the went 260@.600". The machining in throat was God awful and hard to work with. These appear better, however 91.6% is alot for what most guys would be using this for at .600" Street stuff. The DRP's were 89.9%.
Different casting. That's the dart Pro 1 clone, sold as the afr enforcer over here among a ton of others branding it. Blueprint was the first to have it in the US. This casting is pretty pretty much an afr clone, and can be bought with a few as cast runners or a porter casting, they come out of the same mold with different core, everyone's branding them now. There the better China castings. Think aeroflow brands them down under😂. You guys really over pay for the China stuff, you can get this casting cnc straight from the manufacturer, A porter casting , 185 as cast or 205 as cast with a larger cnc port on the way.. Well known mustang shop here sells the 185cnc for 1299 assembled for the pair but probably all China valvetrain since they don't build heads, dart has the 205 as cast version of this in thier shp line.. So afr sells tweaked dart clones and dart sells tweaked afr clones😂
@@WeingartnerRacingSVE heads are Late Model Restorations (rebranded) Chinese cylinder head that released recently. LMR is a Mustang parts retailer for reference.
The casting is actually 205cc when you measure it. At least the set I did was. And the went 260 after I finished "fixing" what I could. Sure 240s before that.
lol afr selling dart china clones and promax and others selling afr china clones... The industry is eating its self, sad state for american aluminum foundries
Great information, my main concern with these types of heads is the deck thickness for say turbo applications say .500 but I like to see thicker than that for lift on the decks. As much as I want to save money it's really temptation to not just go for a say set of 11R for that alone.
except the AFR enforcers have a dual pattern exhaust and 8MM LSX valvetrain actually these are better by about 10CFM at almost every lift. i just watched his AFR enforcer video. these are better and more expensive bare for a reason

Now that's one impressive as cast cylinder head. WOW!
Yes more Fords please
Your GT40 voice was my funniest thing so far today. 2pm- not bad!
Thankyou for the SBF content
Bloody clean , accurate looking castings...
Seeing promax210 and tfs 205 11r would be cool too! Liking the videos
This i wanna see

Great content Eric, thanks for the info....those are great intake flow numbers for a 185cc runner!!!!

Nice video and great description of the sbf project x

Im no superman and i dont port cast iron heads! Lol i wait for it everytime. Keep the sbf content coming brother
I watch all the way through!
is that exhaust bolt patter then same as World products windsor Jrs? because i know headman headers makes headers for my fox but its only for that windsor jr pattern,. this looks like the same one??? and AFR does it??
So could you put a back cut on it? or does the price of doing that make more sense to just jump for AFR's?
just out of curiosity, is it possible to port and fill the exhaust port so its essentially a raised port? would there be enough meat on the port ceiling to allow that?

"Nailhead" bad on Flowbench....good on running engine down track.

That's not bad for a 185 head! Would work well on a 306-331ci street engine. 😁😁
It seems to me that the difference in flow on the intake side between these and the 205s is due to valve size. What do you think?
Yes they are close but it’s not related to valve size.
@@WeingartnerRacing Thanks, Eric
How do Intake port volumes compare between sbf and sbc? I know runner length obviously affects it so what’s the comparison if I’m making sense?
Hi Eric, I am currently building a 347 off of a 87 5.0 and I have the AFR renegade 185's how do those compare for just a street engine. Thanks
January 2025.... I just left your website and it only lists RHS, BRODIX and DART heads for a SBF. I didn't see any Promaxx heads listed under the LS category either. Do you not offer the Promaxx heads any longer? Thanks.
I do you half to call or email. If I listed every head I sell the website would cost a fortune
I wanna see the 220 numbers
Thats insane for a head like this. Are you gonna try to port it?
Dang pretty good for a 185 port now is Ford heads in general are they 20 degree heads
I think so, pretty sure
@@jcnpresser thank you
street friendly Solid roller 331 pump gas stroker and a victor jr and about 10.5:1 with about a 3000 stall ....and these heads....maybe next year....🤔

Please do a review on SVE 185 CNC please :)
I don’t know what that is.
@@WeingartnerRacingSVE heads are Late Model Restorations (rebranded) Chinese cylinder head that released recently. LMR is a Mustang parts retailer for reference.
Do u ever check air speeds?
No
Wow, u actually did something Ford
And the video is not performing well compared to all my other videos right now. Hard to justify doing them.
@@WeingartnerRacing i dont care if u ever do another one 😂
I need those
Engines are engines
How the heck is that head flowing like that and the 185 Chevy head flowed like 245-250?!
The casting is actually 205cc when you measure it. At least the set I did was. And the went 260 after I finished "fixing" what I could. Sure 240s before that.

Nice content and info? How much do these cost in June 2024?
about 1300+ bare im looking at some
You mean to say any stock small block Windsor head 😐
*suck
Flow 185 poryec x sbc
Already did a video on it.
😂a few of us watch the whole thing, minus kids sports
I don't know why anyone whould not buy these lmr just came out with a budget head .
From the same foundry too... Everyone private labeling the same castings and tweaking it here and there. Dart has these too under shp

literally AFR 185 Outlaw Series clones. Flow numbers are exact (1-2cfm off) >= 0.400 upto 0.800 to those.
except the AFR enforcers have a dual pattern exhaust and 8MM LSX valvetrain actually these are better by about 10CFM at almost every lift. i just watched his AFR enforcer video. these are better and more expensive bare for a reason
Are those pro max the same as the 210cc
No they are 185cc
@@WeingartnerRacing no what I ment was is that the same casting as the the 210 or is it a completely different casting
