I just got a stock 225 rebuild kit from Engine Parts Warehouse in Louisville. THe stock cam that comes with that kit is from Dana (aka Mahle Clevite). The cam part no. is2291380. The guy at Mahle CLevite faxed me these spec nos.
It is pretty much the same as Chrysler 3512639, except higher durations

The order for the numbers listed below is

Dana 2291380, Chrysler no.3512639 , Isky no. 152115


Intake Duration at .050 : 203 , 190 , 210
Exh Duration at .050 : 198 , 190 , 210

Int. valve lift: .406 , .406 , .425
Exh. valve lift: .414 , .416 , .425

Intake centerline 106 , 106 , 110


Lobe Spread 109 , 109 , 112


Question: will this amount of extra duration on the Dana cam amount
to any sig. diff. between the Dana and the Chrysler stock?

Are all 3 of these cams gonna be pretty much the same as far
low end torque?

This is going into a 1 bbl, 2 inch dual exh car.
THanks and Peace
