Big cam

[badblazeSS]

i just recently purchased a car with a m6 and the cam that is in the car is a stroker from thunder racing. 248/254 614/625. 2400-7400pb the car will not idle with the a/c on and it is hard to brake at slow speeds. Should i spend money on buying a new cam or just wait it out for a head swap? it is a turd on the low end and i am not a roll racer. thanks in advance

Sounds like a tune issue.
I have a similiar cam in my 402 and have NO vacuum issues. (braking)

As for the idling with the A/C on...that is 100% a tune issue.

that is 100% a tune issue.

It certainly is............223 227 .637 .640 110 LSA...................
No problems.....................

Tune it

i have a guy here in Louisville that is supposed to put a tune on it with hp tuner. i will get the dyno numbers. i know this is off the topic but how much will a stock rear be able to handle?

that depends on what type of carrier is in it and what your driving style is like.

i am not sure what the carrier is. i know that it is a stock 3.42 rear and i'd like to launch it as hard as i can at the track without busting it till i get a 12 bolt. i have bfg drag radials 295/35/18 on th rear.
