28 Chevys - I am running a 292" six with a MY6 trans behind it. In case you're not familiar with MY6, it is a 4-sp., 3.09, 1.67, 1.00, & 0.73 O.D. I have a 3.08 axle set behind this. It's in my daily driver, also have done a couple 500 to 600 mi. road trips in it. Pulls great, I like it. I'm running one big YF adapted off a 300" Ford. This is in my '55 Bel Air. I've seen back yard adapted injection systems on inlines for many years at B'ville. Nice to hear of someone doing it on a street motor.
