Ok, car is almost done so figured I'd post up a build thread.



Found this car for sale on craigslist last summer looking for a mustang for my brother, had a hurt motor and all the owner knew was that it had no compression on cylinder 2. I offered him a price factoring in that I might need a whole long block from Tousley Ford, and thankfully I did cause I'm happy with what I have into it all said and done. So threw it on a trailer and brought it over to my buddies house.



Started with my own compression check and bore scoping. Found that cylinder 2 indeed had nada do to a dropped exhaust valve seat and thankfully there was no contact with the piston.



After a bit of research I found out its a very common issue and it's best to have all the seats replaced with tighter fitting seats. So off the heads went to PER for new seats. They also found 17 valve guides to be out of spec so those were replaced as well.



While it was torn apart I added 98 Cobra intake cams (slightly more duration), 26-spline input shaft and clutch, Metco lower (because I had to hack the stock lower into 30 pieces to get it off since it was siezed into the crank pulley), powder coated valve covers and painted all the brackets, and full Billetflow idler set.



Finally got the car started and running late November early December and drove it home. I recently decided to go with a return fuel system before I got it tuned so I could run E85 to help keep temps down, and of course add more timing to make more power :D.



So that's where it sits right now, waiting to install the fuel system and tune set for May 20th.

Thanks guys. Certainly need to lower it ASAP but just want to make sure it's running good first.

Also want to get the plate holes filled and bumper resprayed along with painting the underside of the hood since I hate that ford skimped on that even though they covered it up. Would like to look into doing a wire tuck as well.

I would suggest the RR pulley, that KB pulley is goin to slip like no other

We'll see. I don't know why it would slip with the biggest upper they make especially with the Gates belt and auxiliary idler. Plus I've heard those RR pulleys just shread the belt.

Like the engine work and valve covers. Really want to do that with some Ford GT coil covers.

I want those but can't justify the price. Might do the GT500 ones powder coated aluminum and black.

3.5 with 4lb with the RR Tensioner. I had no luck with the KB Pulley was fine with the billetflow

Drew removed the notch outta the stock tensioner that keeps it from goin to far down for jon and itll actually tighten it a lil more id suggest that if your gonna keep the stocker
