Need advice on motor combo

HunterisSlow · Apr 28, 2009

Ok Heres my situation. Im new to the mustang world but I have some experience putting together some pretty quick trucks. Then I bought a 90GT with a 306, GT40 heads, GT40 intake, B303 cam, Vortech v2 supercharger, and other Boltons. The car was setup great but it was a little fast for my experience. Due to that I ended up blowing it up after missing a gear. So its been sitting up for the last few months and its about to come back together.
I want to use the car as a dd and I want it to be fairly mild and well mannered. I bought a used 302 shortblock not too long ago. I do not want to run the supercharger on it for sure. I have GT40 heads and intake as well as stock heads and intake. As far as cams I have a stock cam, a cobra cam, and another b303 cam. How would you guys suggest me put this together for a novice driver but keeping the car kinda peppy?

I would use the 303 cam

Use the gt40 heads, intake and the 303 cam, you'll be in the 250 to 290rwhp range with that combo depending on other things.

Personally I'd run the blower, you have it why not put it on, you can make it a dd and not have any issues. The B303 is a horrible blower cam, you'd be far better off with the Cobra cam or a E303 or F303 if your a Motorsport cam fan.

You should be able to make a reliable, 400RWHP with that set-up at 6-8lbs of boost and it will act like a sunday driver.

I'd use the 302 shortblock, cam of your choice and the GT-40 intake, heads and the blower.

lol....that's what he did before and he doesn't want to do again...he wants to work back up to that

My point was having that motor combo did not cause it to blow, and it must have been a huge over rev to hurt the motor.

I just can't see having $4000 worth of parts laying around when he could have a totally streetable set-up that make decent power and the power is there when he wants it. It won't build major boost till 3500-4000rpm or so, which most of the time you are not crusing at...

You can have a mild, well mannered set-up with a blower and have it last for years...if needed you could pulley it down depending on what was already on the blower.

Dont be afraid of the power....

hehe...says one of the addicts

Haha Im used to big 14s trucks. Little mustang felt like a rocketship lol. It wasnt much of an over rev that killed it it just spit the crank out the front. I might just put it together with an b303 cam and the gt40 stuff and see how I like it for now. One I build up some confidence I can swap in a different cam and bolt the blower back on.

How tough are stock 89-93 302 shortblocks? The last one died with 110k on it and the one I bought has about 120k on it.
