engine build

A N/A 347 can easily make those #'s. Also a 331 with a blower can as well.

You'll spend a little more building and installing the 351W in your car, but you'll have a stronger foundation for future growth. Also, a stock stroke 351, or even a stroked W (393 or 408) will be able to make more than your desired power levels with much less effort, and in the end be more streetable, since you won't have to rev it as high or run as much boost as you would with a smaller engine.

That said, you can pretty much open a catalog, close your eyes, and randomly pick parts and make 375hp NA with a 331 or 347. With a little bit more effort, you can make 375hp with a NA H/C/I 302.

Isn't the 1220 one of the smaller Paxton units?

would a 351 and a paxton be much different than stroking a 302? as far as cost goes? i mean swap out the 302 for a 351 probably save a few bucks, swap out the stock 351 cam and throw the paxton on and call it a day until you want more power and then stroke that?

+1 couldnt agree more.

to do the 351 u will need a few different parts that arnt interchangable with the 302 but in the long run its more than worth it.

parts that dont interchange. headers, manifold, dizzy, balancer, flywheel, oilpan, fuel rails

the first time i took my car to the track with an a-trim vortech at only 4psi i ran a 11.84 at 121.81 mph and i have very little suspension work done. this is also with no tune, only me screwing around aimlessly with my pms. as u can see my et and my mph do not match at all. that pass was only a 1.9 60 foot. with some suspension work and nothing else done at that mph id be dipping into the 10's.

now since ive tossed the a-trim and now have a sq-si trim and run it at 6-7psi if i got a good tune id probably be mid 10's with the suspension work as well.

did i mention my car has got a high of 20.88 mpg on the highway as well and i drive it almost an hour and a half to camp pendleton 1 way everyday.
