any benefit to swapping heads?

OP
I know your head hurts but take a crack at this
Cam Timing vs. Compression Analysis
I don't agree with all of it- hell I don't agree with lots of anything but the basics are there
important is is that most tech guys deal with many SBC and SBF and few MOPAR
and there is a big difference between long rod MOPARS and short rod Chevy/ Ford
the bottom line on what he is saying is that intake close and exhaust upon is much more critical on a MOPAR than on a short rod where you have a wider latitude
you want to close the intake earlier and open the exhaust later- a few degrees makes a big difference on the intake close as far as dynamic compression and on the exhaust to get all the power out of the power stroke- especially on a low compression motor
on overlap the fact that the piston dwells longer around TDC means that you have to open the intake later and close the exhaust earlier than a short rod
there is more TIME, DWELL, with the valves open at the same timing than a short rod
so squeezing the lobe centers- well on a MOPAR not so much and a short rod and overlap it's easier to flow your intake right out your exhaust = heat and dilution of the intake charge by the exhaust
If you do not have a clue you end up with a cam that does not do what you wanted eventhough the same cam might work just fine in a chevy or ford

Thanks AJ Controlled Induction can do it and I did it with an earlier version 20 years ago
if you are serious I could buy you a copy
