A recap and some input from some of the viewers comments on the 400 s b c versus 396b b c stock rebuild motors,with cam intake upgrade's
I like your content. gives us Blue collar guys that build in our own garages something to watch that dont feel out of reach. Thanks again and keep the cool stuff coming!
That's crazy cool of you to say that thank you so much!!!
Great content! No goofy music, sound effects or paid advertisements. You just picked up a new subscriber, much respect.
Wow,!!! that was the coolest review. I've got since I started this channel thanks so much, that made my day
Very cool 🤙 have a couple 468's one turbocharged in my squarebody and the other with a tunnel ram in my lowrider. Among a dozen other engines. Have a bad habit of building engines i don't even need smh. Have a pair of fresh 396's and a fresh 406 sitting waiting on an install.
I had a set of those 186 heads on my 69 dz 302 and that with the factory flat tappet solid lift 140 off road chevy factory cam that cam in the 302 i won alòt of street races in my 69 camaro back in the late 70s
Love the big block content! Awesome stuff!
Yeah i've got that addiction also,, Thanks for Watching
That is a great looking car👍🏻
Nice engine builds.
Great information. 👍
I just subscribed to your.
Thanks for sharing.
Have a good evening.
Thanks for the sub!
Great video’s! I have a 71 400 that I wanna go 406 with you are giving a ton of good info on specs. I’m definitely paying attention thanks a lot.
Im also building a 406 i think im going to puta set of promaxx heads on it best bang for the buck😊
I've got a friend that's a cylinder head porter, he is crazy about those promax heads,, So I know they must be good
You're the man! Thanks for Watching!!
Happy New Year! Can you drill those double hump heads with the 400 steam ports?
yes
Happy New Year DZ!
Happy New Year DZ
I have a 427 0.60 over so a 439 about 10.6 to 1 snd a howards hydraulic roller a lil smaller then your cam same afr heads it made 661 hp and 605 torque @6400 rpm then maðe a few more pulls 647 and backed it up with a 648 i love my big blòcks
Wow that sounds like a hell of a Engine
Everyone sniffle ing, and it's not even their motor. Keep doing what you are doing. I think you could sell a few of those 468 motors.
Thank you so much,, I drag race and assemble engines. But I'm not very good at making videos. Thanks for watching
Excited to see what the trick flows do on the 406 I’m doing the CNC DHC 200 on my 306cid and shooting for 9k rpm. but my 409 (0.040 over 400) needs a set of heads when I’m not at the salt. And been looking at the 175s for that due to the lower rpm and drivability.
I'm planning on hitting the 406 small block with factory, 186# casting's first and then next month doing the trick flow heads
@@dzperformance7360 what compression ratio are you running as the aluminum should allow a higher static providing more hp
@@dzperformance7360when can we expect video? with 186s
That right at the same hp. My 0.60 over 427 made the best of 661 hp 605 torque and later that day 647 then 648 with the afr heads and a 950 hòlly the cam was a howards 235x241 @ 50 and 618 lift 108 lsa good power simply combo
Thanks!
Looks like you got your windage issue fixed from the previous videos where you were losing a lot of oil pressure...I assume you drained some oil on this test...
I hope the dyno bank 2 AFR is wrong good lord it's lean....
I've run the race rites NA and boosted and the 265 AFR ( and others) as well.468 and 496...my AFRs were milled to 11 to 1 on the 496..made 686hp at 6700 with a Edelbrock Street Ram converted to EFI and we made the top kinda similar to a holley hi ram..
I also run direct axle oiled morel solids on a custom billet core hydraulic roller profile with additional pressure about 200 seat 580 nose...zero lash cold .006-
008 hot...added 500rpm to peak when I upped that pressure..
Then I added a F1A-94 and actually run on both in car and 7600rpm was no issue on the 468", there wasn't any "nose over" it ran that way 6 years, near daily driving it's the ONLY way I'd run a BBC again...hybrid hyd/solid period...I tried every lifter made from isky EZRoll dissimilar metal $1300 crap all of em morel, Johnson good lifters they all failed actually driving it around a lot with " street solid rollers" all of em bigger wheel, direct oiled did add life....
I tried ALL the lifters and oil weights and clearances and preloads...it's gonna tick hot or cold take your pick and still roll over at 6200 no matter the cam...lol..
That hybrid setup was money 0 lash during summer cold, done singer sewing machine for YEARS took well over 1000hp ( 17psi ) sold it 6 years later and it's in full size blazer still get driven going on 3-4 years now....different intake and carb is all......
Believe folks for BBC it's the ticket, Herbert adds 100 to use a billet vs Sadi core to any of their custom cam you choose the lobes....morel direct axle oiled and it will spin up, sound great and live....
Sweet to see it being used here
The 468 has the bore of 4.310"... Of course, your 468 is of no comparison to my race 468. Mine made 776 HP
at 7,500 rpm. I changed some things and now it makes 800 HP. 4&7 swap cam by Competition custom ground. 1.8 ratio on intake and 1.75 on exhaust. Big blocks usually have more duration on the exhaust, since they make more power on the exhaust side. My cam has the lift of .793" and 7.46 on the exhaust, lobe center 112°, made the most power on 109° Brodix round top intake, 4150 bolt pattern with turtle. 2" HV 4 hole tapered spacer to 4500 carb, carb is a 1050 cfm #8896. Eric in OK has all my parts that he ran on the Dyno. You cannot get that intake anymore, comp. 12.3. Brodix 310 cc open chamber heads, cut down
to 108cc. 2.250" intake valves and 1.88" exhaust. 50° on intake valves and seats. They do not make that head anymore. It is not CNC'd. Intake and heads have been port matched. Std. length rods, 6.135".
Yeah, I caught that also but I didn't want to redo the whole video on the mistake made on the bore of the 468
Thanks for watching
I’ll take the 396 ! Would go great in my 69 SS Chevelle !
I'll be done with it by late spring,, It will be for sale
It's for sale $3,800 816 213 7204 text me if interested
I wonder how well a 396 would do with the afr 265’s
I bet it would pick it up but I don't think I want to invest the time
Will the custom Lunati cam supply enough vacuum to run power brakes on a street car?
Big blocks are so easy to make power with.
Probably not, If you had a 496 with pretty good compression like 10.5, I would say yes,461ci with 9.8 I would say no.
I'm excited to see what the 186 castings will do. I estimate 380 HP and 430 torque.
Sometimes i'm over optimistic but,, I'm calling 420 hp 490 tq
And by the way, I'm stepping up to an Edl. r p m manifold on the small block
I like to underestimate 😊
@@dzperformance7360when can we expect the video to come out?
I'm going middle ground 400/450 that's good safe numbers for the combo I believe
Are you DZ302?
No,, D.Z. is my Initials/ my name
@@dzperformance7360it was a joke 😂
*467
That's the actual cubic inches but most call them 468
