So I guess the first question is are these the same? My intention is to send the 68 block out for rebuild and swap it in. That way I can still stay driving all summer...))
Get an estimate for redoing your heads.You may come out better buying a set of aluminum heads on dollars alone.The performance would be free.The sidewinder heads mopartsracing - Sidewinder Cylinder Heads For Big Block Mopar
would be hard to beat if the bill on your heads even comes close to what these cost.Doesn't mean you have to go crazy with everything else.
Would allow more compression safely.Use your stock rockers and manifolds and maybe a comp 260 cam (or the like) and the smile will never leave your face.
Well, my project got stalled..driving the son to his girlfriend and my muffler dropped to the pavement...looked good underneath but it has rusted at the rear connection to pipe. Sooo...I'm swapping exhaust manifolds right now to the ones off the 68 and getting a full dual exhaust put in. 2.5 true dual with flowmaster 40s
