Hey Guys

Just wanted some advice on the .528 purple shaft

would you guys run it straight up or advance it 4 degrees ?

Projected spec's looking for 500+ HP

comp 10:25 need's to live on pump gas.

Edelbrock aluminum RPM's 82cc

Edelbrock rpm intake gasket matched

Its going in a 4 speed 70 Dart .

Rear is 4:10's currently but i have a pumkin with 3:91's and 28 X 10.5 tire

Thanks



I use nearly the same combination (RPM heads, Victor intake, 4.10 gears, 4-speed, etc). Except, I run the .590 solid from Mopar, widely stated by Mopar to be completely un-streetable. I run the camshaft EVERY DAY on the street, and it is aggressive, but no where near un-streetable. .528 would be a kitten, I would either go with the .557 or .590 at a MINIMUM if you want to build serious power and have a ridiculous idle sound to match..
