Howdy,
Being on the road away from the garage means back-burner projects kinda float to the top of the whole thought experiment heap... I've stockpiled a stash of parts for a 3.0L destroker (3.800 bore, 2.660 stroke) built on a stock block for Bonneville. Land Speed Racing (LSR) means sustained engine power over miles and minutes which leads to my question of which is going to be a more durable Buick Turbo6: a 275hp motor that has to run to 7000rpm to reach the speed or a 310hp motor that only has to get to 5500rpm?
Difference really is in the transmission, an OD is going to cost more power but a TH200-4R's 0.67:1 ratio brings the rpm down and lets me run a bit taller rear gear vs. a TH350C which takes less power but requires a shorter rear gear and more rpms.
Thoughts?
