I spent some time on my 1978 440 SE ram charger that makes a blistering 120 rwhp. I've got it tuned, it runs very smooth, starts off the key like an EFI vehicle. , it just makes no power being a smogger 440 at 3800 feet of altitude. I did a leak down and its less than 8% across all the cylinders, the cranking compression is all in the 120's. The pistons are most like down a 1/4 in the hole at TDC.
The motor runs well enough I am not going to do a full overhaul, so what I thought I should do, is throw a set of heads on it to give it a bump. What aftermarket head would be the best for this to give it a compression bump and not end up with quench issues?
It looks and sounds to me like its got had the full edelbrock performer package thrown at it, it has performer intake, 1411 carb, the timing change is double roller, and it idles with a mild lope, so I would hazard a guess its got the performer cam in it.
