Guys,
Bout to start ordering all the stuff to put this motor together. Here's the spec sheet. '84 4.1L "484" production block, .030 over with Venolia pistons, stock turbo crank and rods. The motor will be receiving a fully ported set of TTA heads with big valves. Fully ported and port matched intake. PT-70 with P-trim exhaust wheel and a Precision .63 housing. 3300-3400 stall 9/11 lockup from Bruce Toelle. The rear is a Moser 9" with 3.25 gears. I'm stumped as to what cam I should go with. This will be a 25% street car 75% track car driven on the weekends occasionally. I don't know if I should go roller or not, or which size. I have been told and it makes since also that a cam that is pretty big in a 3.8 won't be so radical in a 4.1 b/c of the 10-18% more cubic inches. Anyone out there with any good recommendations? Roller or not? Thanks.
