Not many responses or visits either I think but I will ask. I have been doing a little research on Stovebolts and a few links shared here and there. My plan is to replace my stock 216 motor with a 1958 235 which I will have rebuilt or at least refreshed. I have located two different T5's one in a Mustang the other in a S 10. Unsure but I think both are pre 88's. On Stovebolts it was suggested to use S 10 if you want to keep bench seat. Was wondering about gear ratio's which I don't know Jack about, it was said to make sure my differential would be a good match. I have no idea what a stock 47 had. It was also said the T5 would bolt up to my stock bell housing. I read where different T5's had different output shaft splines. I would really like it if I could buy this whole S 10 and everything swap perfectly. So I guess I'm just asking what others have had to do to make a swap like or similar to this. Would my stock diff ratio be stamled on it? or maybe a tag? What about using my stock driveshaft and diff ?
