I just finished up my new motor in my 89 mustang GT and will be heading to the dyno next weekend. I was wondering if you guys would like to take a shot at what type of numbers I will lay down at the rear wheels. Here is the combo:

-308 (5.0 block bored .040 over)
-stock crank cut .010
-worked stock rods
-BRC Forged flat-top pistons (compression is 10.5:1)
-X-303 cam
-CNC powerheads (cnc ported e7's w/ 1.90 intake/1.60 exhaust valves), milled .040 to make 58cc chambers)
-double springs good to .590 lift
-proform aluminum roller rockers 1.6 ratio
-Edelbrock performer RPM intake
-70mm throttle body
-76mm C&L mass air sensor
-24# injectors
-AFPR set at 45 psi
-BBK equal length headers running into off-road 2.5" with single chambers
-timing set at 12 degrees advance
-backed by a t-5 and spec stage 3 clutch

**I will also be running nitrous but we wont include that here.

260-265 at best, you need good heads to make some good power.
