Well I blew my motor about a month ago and I bought stock 98 gt shortblock that has new bearings in it...only has 40k on it. My car is 1997 Mustang GT Convertible Automatic.....I'm doing the P.I. swap on it also. My current mods are MAC long-tubes, MAC h-pipe w/cats, MAC Flowpath Catback, BBK Cold air intake, Steeda Pulleys, Granatelli plenum, BBK 75mm throttle body. the P.I. heads are completely stock .
I know the compression will be raised to about 10.5 and going through a Automatic (was rebuilt 30k miles ago) will lower it more than a manual. Plus my 4.10's will take like 5hp and 5tq away.
I'm hoping for about 260hp and 300tq at the wheels....
I won't be able to tune it for alittle time so I know i won't get the full amount out of it.
What is your estimate untuned??? Tuned???
