I've tackled most upgrades on my blazer except for engine upgrades. I'm ready to do a real performance build up on a SBC but I'm not sure which way to go. As with any investment I'd like to do this once and get it right. I found an engine recipe that is almost too good to be true on the dyno but on paper the parts seem mismatched. So my question is do I build a SB that has been on a dyno that has a torque curve so fat a diesel would be jelous or do I build a 383 that makes decent power and is well within the limits of popular thinking and theory and be happy with it.
