Why would my motor feel like it has more power with my 346 heads shaved .030 vs the new 440 source heads? It has KB 400 pistons and both heads had the same head gaskets.


I think something isn't set right. Gas pedal,,timing,,puel press,,float level,, rocker geometry,,
The other issue is how fast did , and how fast does, it run the 1/4?
