Thread: Performance lacking?

with ported heads and a cam you should easily be able to run at the very least a 3.4

There is a point where your maxing out the WOT advance...and you aren't gaining anymore power...think, 23-25* on a blower car.

I ran 23*...car pulled like a rabbid ass ape.

On a 3.0"...

Regardless, I'd run a 3.2"~ pulley and 18-20* at WOT...that way you should be able to put down a solid...what...40-ish TQ dropping a quarter of an inch in pulley size.

anyone else have anything to chime in on this?

my stock fueling system should be able to handle a 3.2 correct?

I ran a 3.25" on stock injectors no problem...if that helps.

Every car is a little different...some cars have run static on a 3.25", hell...some on a 3.4" with aggresive enough tuning...then other cars have ran a 3.1".

It's hit and miss.
