AFR MOPAR 340 HEAD TEST!

PRH said
I’d expect an even bigger difference in power if the test had been done using a short block that could fully use up the air flow of both heads.

But as for the AFR’s themselves……”so far, so good”.

10-20 more degrees and 0.050"-0.100" more lift would really wake that 340 up, I feel a lot are glossing over how small of a cam their running.
