I know it's likely a broad and vague question...but I'm looking for a general answer beyond "Yes". lol. Here's my engine specs: 65 283 from an Impala...nothing special 500cfm Edelbrock carb Performer intake points distributor mild freshening.....new gaskets, lifters, rods. Cam looked good very mild honing on one cylinder to get some minor rust scale off backed up by a th350 and 81 Trans Am rear.... 3.08 ratio I got ahold of another 283 with the Power Pack heads, and was wondering how much more get up and go this might impart to my meek little engine? I'm running it in my 50 Chevy 2dr sedan. It doesn't have a whole lot of low end power, though.
