I have a built 383 with 10.5 SCR that made 561 on the engine dyno. Well, I want more! I was thinking about a D1sc at 6-7 psi. Can I do this safely on 93 pump? I do have a good sized solid roller to bleed some pressure and efficient aluminum heads.

Would I need to run meth injection?

your cam cannot change your compression ratio. As far as running low boost you should be fine providing that you run 93 octane fuel with a decent intercooler.

You can easily run 8 psi with your compression ratio, the carb helps to cool down the inlet air temps and you won't need methanol injection. Give me a call for a great price for your SBC. Bob

How does the carb cool down inlet temps?

The intake manifold becomes a wet manifold with a carb, and the fuel going through it drops the inlet air temps. Bob
