    Hello everyone!

    I recently acquired a '79 Z28 rolling chassis from a guy who was building a turbo LS/T56 setup for it. He abandoned the Z to put his big money power train into a '92 RS with sentimental value instead. So my Z already has the hydraulic clutch setup and modified trans tunnel to accommodate the large six-speed, but I simply do not have thousands laying around to drop on all that jazz. So what other options do I have that are compatible? The car has no cross member or driveshaft either.

    I found a T5 with early SBC bell housing for $300 but it sold within hours.

    Searching these forums lots of people seem to be looking for bits and pieces for Super T10.

    I learned to drive on a manual trans but have never had one in a Camaro. I have chewed up quite a few TH350's though. I'd realllllly like to have a fourth or fifth gear for comfortable cruising.

    I won't be racing this car in any professional or sanctioned capacity; my work schedule simply won't allow it. I'm being very optimistic for a ~400 WHP/6500 max rpm powerplant so don't necessarily need "bulletproof" stuff

    I would put in a Super T-10 in it .Since that what came in those cars. I have a 1979 Z-28 RS Pro-touring car. And I have done the Turbo 350 /Super T-10 swap..Because they have a couple of gear ratios available Stock) 2:64 and or Aftermarket )2:88 first gear. With a 3:42 gears .With a 500 HP plus Supercharged small block Chevy. And as long as I keep my foot out of it.(Of which be awfully hard at times)gets around 25 MPG at 2600 RPM with a 26 inch tall tire.Have fun. 130044932860518017_26257430996_o (1).jpg

    Is the Super T-10 compatible with a hydraulic clutch, or would I have to convert over to mechanical linkage? I have no idea if these cars came with hydraulic or mechanical clutch; again, I've only had TH350's in a different '79

    You can easily run a hydo clutch using stock input bearing retainer too. I am using a ram on my ls/super t10 combo

    A 3.42 first gear ST10 with a 3.08 rear end would keep your highway RPMs low. but this is the weakest of the ST10 transmission. Those cars came with mechanical clutch linkage, but you can convert it to hydraulic if you want.

    If the 92 RS was a V8 T5, grabbing that would be an option.

    No way would I put effort into not having OD.
    Save up for something you actually want, then save on gas.

    What rear gears are you starting with?

    I have modified my mechanical linkage with Heim Joints it makes it real slick.
