    O.k so I have a NWC T5 from a 92 S10 I want to mate it to a stock 283 sbc I have. It seems some people think this isn't a wise idea. As long as I don't drag race this combination why not use it? Thanks for the input. -stick

    If you're going to abuse it, it's not going to last very long. Otherwise, it should be fine. Make sure you get a decent shifter with adjustable stops. With the stock shfiter, the aluminum shift forks act as the stops, and they aren't very strong.

    PM hotrod roadster with your questions, he's been running and beating a T-5 behind a 327 in his A highboy for several years with no problems.

    I run a WC T-5 behind a 370HP engine and flog it often, works great! Go for it!

    I ran a stock non WC T5 behind a mild 307 with a 125 shot and it held up fine. even with 5 grand clutch drops in a 3500 pound car:D

    You might find the 283 doesn't have enough torque to pull high gear.
    Also depends on what you are putting it in.

    The easy answer is try it and see.

    I've been readling the posts here for awhile and figured it was time to write. So I'm building my 89' T5 out of my s10 with the 4 banger and putting it behind a 1967 283. 62 cast iron bellhousing using a hydrolic tbearing for the T5 vs. fork. Stock 283 flywheel and clutch which is 10 spline, but I'm using the jeep 21 tooth input shaft which is 10 spline. Cutting it down to 8 3/4" or so. Of course my truck sports a 4.56 with 32" tires so the 4.03 gear cluster is desireable, but I am changing the O.D. gear from a 51T/25T to a 61T/25T for the .72 5th ratio (61T/23T will give a .66). The 283 is a 195HP at about 230 to 260 ft. torque... ish of course. As with anything, if you abuse it... it will break. Lord know's I've done several 5K dumps when it was a 4banger and would burn the 32's till I ran out of RPM and chirped my way into 2nd... But spinning the tires doesn't break things. It's when you hook up. I sport a light S10 with a way heavy front end now. I'm guessing like anything the total application is what you have to look at. Not just part of it. I kept the T5 as it came in the truck, fit's the truck and works the speedo, and I'm not building a hot rod. I was told the major reason the 4.03 gear cluster is not very v8 friendly is due to the torque multiplication. The more torque the motor has, the more it is multiplied by the gear set. That's why you see 2.95 (?) for the v8's and the brief 3.35(?) for the bigger v6's. Don't quite me on the numbers, consider them ISH... Anyway, that's my story. So damn the torpedo's... full speed ahead... Oh yea, and it's a q-jet 283 now vs. 2bbl... but that's another story...
