Bare with me this is my first post. I have a stock 350 that I want to build. We got it from a family member who has multiple sitting in his shed. But we want to run the comp magnum 292 cam in it. We are going to match it with 64cc 200cc Heads. On top of that we are going to run a performer rpm intake with 650cc Edelbrock carb. We will also be running a 3000 stall with 4.10 posi.
My question is will this setup work well or end up being a dog? I am hoping 400hp. Any help will be greatly appreciated. Thanks in advance.
From the factory stock 350's come from 145 hp to 370 hp, needless to say the internals especially the short block are a lot different so you need to know what you're starting from. Since GM puts a lot of the compression ratio into the piston, simply changing heads may or may-not make much if any difference in compression ratio. Big and the bigger they are the more compression they need and the Comp 292 cam likes a lot of compression.

You can find out what the engine is by referencing the build code on the flat just below and ahead of the passenger side head. Other indicators are the casting numbers for the block, on the bellhousing flange, drivers side, and the heads, on the head facing up with the rocker cover removed.

Building an engine today is very different path than the good old days since compression is limited by fuel that is available. For the street this leads to shorter durations with more and faster lift rates wider LSAs and less ramp time leading to and away from the lobe. This vastly improves power especially with modern chamber heads. Getting 400 hp from a 350 today is easy with Vortec style heads, 9.5 to 1 compression, a Comp XE268H cam, Edlebrock Performer RPM intake, a 750 carb, 1.6 ratio roller rockers on 7/16ths studs, and 1-3/4 dia long tube headers with a 3 inch dia collector.
