The Stovebolt Site Forums The Shop Area Engine Shop t5 on its way, rear end?

i bought a 87 s10 t5 not sure what the ratio is yet. it is being shipped in. most of the charts iv'e seen only go up to an 85. i am keeping the 235 in the 54 3100 and just want to drive 16 miles on the highway to work. i have several rearends i am looking at. one i think out of a 55 that will bolt up. the owner thinks it is 410, checking on that. i have one avalible out of a 69 chevy truck. some modification required from what i read. owner thinks it is 308. i hopeing for 373. i have read lots of post on here on this and just hope i am on the right track? any advice would be appreciated.

This should help to ID your T5 if your other sources end at 85'.

That is a good chart Randy linked to. The 55 rear end is probably a 3.90. It will be real good with a .072 or .076 o-drive. The 3.08 would be no good. The 235 wont pull it. With the 3.90 you will cruise comfortably at 60-65 with bursts up to 70 if necessary.

thanks guys. the guy i bought the t 5 never got back to me, but it is in transit. should be here the 12th. i bought at 373 rearend today. its out of a 67 chevy pu. probably forgot to mention my has the closed driveshaft. looking for some new perches and shackles? to install the new rearend. cody
