The other day I heard the one where you need to run two points higher compression with aluminum to make the same power as iron. It was like 1992 all over again.

The 509 cam is still the best.

The valves have to be in the "factory" location and the heads have to look like 906s or they're not Mopar heads.

Let's not forget the EXACT shade of engine paint or it isn't good enough!

And a camshaft with a splash of purple paint is just flat magic.

Anyone know where I can find one of them 340 Wedge motors? They made a lot more power than a plain ole 340.

Don't know about the 2 points higher thing ( sounds a little - extravagant, but all else being equal, aluminum dissipates the heat faster than cast iron and HP is all about making heat - so ......... you can run more lead with aluminum ( if your motor like it - mine does ) and still stay out of detonation. beer
