'86 short block buildup?

The 86 short block is actually a good engine. Forged rods and pistons, and a relatively high comp ratio of 9.3 to 1. The Trick Flows will fit fine. I was running an 86 long block with stock heads and an E-303 cam, and the car ran 13.8 with drag radials and 3.55 gears. And it was carbed. I called TrickFlow, and they said it would fit just fine, and just as well as the later notched pistons. They said it didnt matter since the Trick Flows dont use the stock notches anyways since the valves are canted. I would think my old combo with trickflows and slicks and some more practice could easily have netted 12's. Imagine if I had 4.10's!! I'd run the stock intake for now since your going 351 later. This will save you money since the different engines require different intakes. I think your setup with 1.6 rollers, E-303 or equivalent, TrickFlows or any 1.94 valve head, exhaust, and 3.55 or lower will net you very low 13's or 12's with slicks.

Dont waste your money on that TMOSS/Thumper crap. Its all hype. If you must have an intake, just get an explorer intake.
