so far i have built a megasquirt for a hybrid small block chevy (when i say hybrid i mean a 71 block with lt1 heads and intake with a distributor mounted out back water passages in each ends of the heads for return back to the radiator and a lt1 throttle body out front with 42 lb. injectors. i will be building a 250 six (where my heart has always been) and using a megasquirt also. that will be next year when it is finished but i promise it will be fast. real fast!!!
