Thats sweet. The lil tires are sooo cute. Are you planning on running a chevy 5 speed tranny? Thats a T5 from Borg Warner, I dunno if there is a difference between a truck T5 and a car T5 but the ones in cars are P.O.S! I guess though in a toy it would be fine cause most the stress and torque is behind the t-cases. I'd do a lil research if you havnt already. Wouldnt want to put a garbage tranny in there. How much for the Couger and whats wrong with it? Gees, this is all I need another toy.
I think the T-5 would be fine behind a 4.3. Chevy put them in 3rd generation IROC camaros with 305s and people killed them. I'm running a T-5 and it seems fine and my motors a little built up. If you dint beat it up it should be fine
