I will have a 302 block, I will be getting it from psiperformance tuesday. Dean said it was out of his '66, has tri-y headers and was rebuilt less than 2k miles ago. The engine I have now is a '65 289 block, and confirmed '65 because I had to replace the valve cover gaskets and check the date on the heads while I had the covers off.
When I get the 302. I'm going to put the edelbrock performer 289 intake and holley 4bll 6oo cfm carb I have on it.
so would it be better to swap my 289 heads onto the 302 to give it higher compression being that 289 chambers are smaller?
