Hello all, Grant here. I have the original 235 in my 59. I have a 3:42 10 bolt out of a 90's Caprice, with a Saginaw 4 speed, late 70's vintage, that I plan on installing behind the 6. I have the needed driveshaft yokes from late 80's S-10 Chevy. My question is... is the bell housing plane of the engine at the same location if it's a 6 cyl or a V-8? When I had the trans out last summer, I did some preliminary measuring, and found too that the Hurst trans shifter will not fit the floor insert. I have bucket seats, so it is not as important of location with bench, but the truck is so clean that I want to cut as little as possible. My long term plans are for a stock v-8, with the 4 speed. If the bell housing planes are the same, I will only need to cut the floor once. Otherwise I'll wait for the 4 speed and the V-8. What do you guys think? Grant.
