Re: metric 200 chevy bolt pattern
Using an overdrive automatic , has a lot to do if you use 4th gear . If you don't , then it makes more sense to run a 3 speed and take advantage of lower weight , and less rotational inertia .

Re: metric 200 chevy bolt pattern
Way back in the mid 80's when Oldsmobile was out there racing a lot of 307 Cutlass's , the Stockers were running with a 350THM . I was able to get them to give me one so we could develop a 200-4R to race . To use 4th gear, I was running a 5.57 rear gear , most had about a 5.13 . At the time there was no support for the 200/200-4R so converters were a problem . Also a .67 ratio , 4th gear , dragged the engine down too far . The problem was fixed by swapping in a .72 ratio overdrive from a transmission that GM built for BMW . Now there is great support for a 200 , so converters , and lightweight internals are readily available .
