Default 5.3 with precision 70 in 3rd gen formula

Hey guys I've been lurking around the boards for awhile doing a lot of reading. I figured it was time to post up my build. I have an 87 Formula that I'm putting a 5.3 in with 317's, custom turbo cam,ls2 intake(was on motor when I bought it), 90mmtb, a Precision 70hpq with .96ar. I will also be running e85. Here"s a pic of the motor in the car and the car.

I'm sure it'll end up being faster than the buick motor was and more reliable.

Thanks man. The manifolds are shotty h2 headers that I had laying around the shop. I had to cut an inch out of the two front tubes on the driver side so they would clear the steering shaft and I put the v-band flanges on.

I got a good deal on the motor already put together with the custom cam double roller timining chain hardened push rods dual valve springs titanium retainers. So I giguered I'd run it for now. I do like the jy build its way cheaper than the Buick stuff I had in it and I think its going to be more reliable.
