Thread: help....thoughts? SBC 400

What is the piston part number?
What is the block deck height?
Are you stuck on 64cc heads? Profiler makes an excellent and affordable set of 70cc or 72cc heads that will support 500 hp in your 408.

Keith Black makes a nice hypereutectic piston that would produce about 10.5:1 SCR with a 72cc head. Most builders will agree that 10.5 is the limit with today's pump gas.

I would cut the block deck height to 9.008" (zero deck with the KB pistons shown above, when used with 5.7" rods. Scat 25700P will clear the cam lobes.), then use a Fel-Pro 1014 gasket (0.039" thickness) to set the squish at 0.039". Any aluminum head manufacturer will specify a composition gasket to be used with their heads. The 1014 has pre-flattened fire rings to help prevent brinelling of the heads, as well as having steam holes.

If you are open to this suggestion, I will explain the details of this build for you, along with the proper cam, intake, carb, headers, etc. Are you open to laying out 600 bucks for a retro roller hydraulic cam and roller lifters? Howards makes an excellent product for the price.

If we never hear from you again, you should know that the heads will have to be drilled for steam holes. The manufacturer will drill them for you or you can do it yourself.....

Piston part is 400AB (i think, at work right now cant remember exactly) sealed power pistons. Havent actually measured deck height other than how far down the pistons sat. How do I measure the deck height? SBC stock is 9.025 correct?
Yeah on the 64cc heads, good price, probably not the best available by any means but the price is right $700 comeplete for the set with 2.02/1.6 valves and springs set for .60 lift. They will be drilled with steam holes already. Yes on roller set up, have been looking at howards actually. I just dont know how to correlate the numbers to how it will sound. I want the perverbial "best of both worlds" a nice lope with usable power band. carb i was thinking along the 750cfm route, intake: edelbrock performer, long tube headers. Looking to build a street engine that will fry the tires when the time is right, and sounds "healthy"........ based on cam then i would choose the correct torque converter for the 700r4.
