hey guys, i'm mating a th400 and sbc converter to a 98 LS1 flexplate. At the parts store they have a bolt set for a TH350. the specs are 0.375" x 5/8". but their website (oreillys) says there is another bolt set for a TH400 where the bolts are 0.375" x 1/2".
Is it ok to use the 5/8" TH350 set? My LS1 engine should make 400 horsepower give or take a few hp.
I wanted to check with you guys before getting them. Don't want to shear off bolts or have something else weird happen.
