I've been wanting to know something and NOBODY'S answered me. You sound like you have enough knowledge to possibly help me out. So,....here's the question. If a man orders an engine block and all the components to build a turnkey motor and assembles it himself. Then,.....orders another block and all the components for a second turnkey motor that would be identical in every respect to the previously built engine he assembled,....only this time,....he sends it to Keith Black. Or Pat Musi to have it assembled. Is one of those motors gonna make a considerable amount of horsepower more than the other. Thanks for the answer if you got one. If not,...well thanks for responding anyway. God Bless my friend.
Stroker engines are pretty involved. If the guy building it himself managed to clearance everything properly and it didn't blow up it would run well. The custom cam and custom port work that these known engines builders do would make the extra 30-50hp over out of the box heads and off the shelf cam.
And when I'm talking cost include carberator 600+ headers 700+ pulley system 400 distributor 300 msd box 200 harmonic balancer 200 to the cost bet this engine is over 12,000 dollars without what is mentioned above with them added bet it's around 15,000 give or take
I have actually built a 427 out of an old school 400 small block after all the machine work rods crank Pistons heads camshaft Etc I had almost 10 grand in it and I may be leaving some out however horsepower per cubic inch and a small block package you cannot even compare specially a pump gas motor with no power adder.
@@SketchyAtBest And it's a good deal, i've got more in my 17* pump gas 399ci with close to the same dyno run. The 427 beats me everywhere by a little till 6000 then my heads and cam start talking.
What solid lift roller camshaft would you recommend for a 10:5.1 comp. ratio 427 sbc with 65cc AFR 210 Competition ported heads , super victor 4500 flange intake, 1050 dominator carburetor, bracket race motor? I want to run92/93 octane pump gas. I will be cruising on the streets occasionally but I don't care if it is a street friendly driver. I want the most power possible on 92/93 octane pump gas. If I can find a piston that would put it around 10:8.1 I'd be ok with that comp. ratio on pump gas too I would think. Just don't know what solid lift roller cam to use. Any suggestions would be greatly appreciated. Thanks!!!
Don't know what you ended up building but my 10.7 to 1/ 89 octane 399ci. on a Dart Little M with 17* Brodix C-Series heads 261cc./404 cfm makes 641 hp@6400 and 560 ft lbs @5700 and is a blast to drive in my 94 Sonoma. Solid roller is 260/266..........679/668......110.
All new. Dart SHP block, forged rotating assembly, AFR heads, ext. No junkyard parts here! I have personally been considering getting a short block from dart. Not only is it all new high quality parts that can handle decent power, but their block has priority main oiling so if you're living in high RPM's for awhile, like on a drag strip, all the important stuff see's oil first. Pretty cool.
While I'm impressed with 630+ horsepower on pump gas I'm thinking there are some pretty expensive parts being used to make this kind of power the heads have to be pretty expensive not at all knocking this setup but would like to know the cost to build such a engine because I'm thinking a 416ci LS engine can make this kind of power maybe 650 hp range run cooler last much longer and be more streetable and idle better at close to the same price maybe a little more while it may not make as much low end torque as this engine below 3500rpm my thinking is on the high end above 5000rpm to 7200rpm the 416ci LS engine will out do this engine the only down point will be it will need a higher stall torque converter and lower gears for it to really work but it should pull much better on the high end or at half track in the quarter mile hell stock 376ci engines with stock CNC ported heads and a good hydraulic rollor cam can make 560 hp with stock rods crank and pistons and turn 7000rpm and run 10.80s in the quarter mile in a 3400 pound car with driver and be driven on the street and last a pretty long time if not beat on constantly for around 11,500 dollars complete brand new crate carberator pulley system headers msd box comes with hardened pushrods and a SFI harmonic balancer for 1800 more you can get some good connecting rods and forged pistons with valve reliefs

@they're not us no but I've been racing the same car for 35 years and it's on the fourth engine sorry brother I'm only the driver my friends build it set it up and l run the shit out of it and thats just the way l like it so l have somewhat of a idea of what works and what doesn't how by the time sheets and feeling it in the seat of my pants

Wow, just wow…credit to you!!!
Lot of skill, knowledge & experience gone into that. Worth every penny
One of the best set of heads you can buy for a small block bar none!
perfect for my 71 Chevy!!
That's a nice curve. Should run well with that peak spread.

Sounds about right. I have about 12g in my sbc with similar parts
Well they don't have a pulley system on this engine but if u want a nice setup like March pulleys ur probably over 2k
Yup my 6 liter was $19,5. 280cc brodix br bp heads aint cheap lol.
do you guys build crate sbc engines with the new EFi setups like holley sniper, Fast 2.0, or FiTech throtle body style fuel injection?
We sure do, We offer any Holley EFI set up on any of our packages
@anonymous aftermarket block, no
@anonymous aftermarket blocks have larger coolant passages as well as more cast iron material to help reduce heat

How much does this particular 427 small block cost??
