Also will this trans hold up with this new motor? Helpppppp
I think everybody is missing the point, what Allen is asking is how will the car handle? well! I you install an all iron engine, your car will handle like a pig compared to the small block. If you install an aluminum engine, the car should drive almost the same with much more torque of course. An iron block, aluminum heads and manifold should be fine provided you re-tune the suspensions. It all depends what type of driving you like, If you like to drive on canyon roads then the SB is the answer, if you drag race then of course a BB would more appropriate. Most cobra owners I know think the best combination for a road car is the big 4" coil spring chassis powered by a small block like the old AC 289.
