Re: Dyno Results:Holley Stealth Terminator v Holley 750cfm
my 406 wanted 38* of timing. As mentioned, small block chevys need timing. Especially with older heads.
If you want to make power, the first thing I'd recommend is getting a good aftermarket aluminum head. I am partial to AFR but there are tons of choices out there. Those fuelie heads were fine back in the day but that is now 50 year old technology. You upgraded to EFI so why run it with 50 year old heads?
What is your HP goal and what is your budget?
