Looking at buying another Mustang and could be this weekend. As far as my plans for the car I want to go a diffrent route from the last one I had. I did the supercharger route before but now I want to build a nasty N/A combo set up for the track. I was thinking of a high compression 347 w/ a nice tranny/clutch set up.

Just wondering what those of you w/ 331-347's are putting out for power w/ your set up and what your track times are if any.

Just installed my new 336 c.i.d. engine in my 85G.T. No track times yet but I do have the dyno results. The car dyno'ed 387 H.P. AND 362 Ft Lbs. of Torque to the rear wheels. These are N/A Numbers. Just a single 4v carb set-up. The block is bored .060 over hence the 336 #. Looking to go 11.50's with this set-up.
