    go get a t56 or if you don't want all the work get a tremec 5 speed. Richmond is also coming out with a new five speed or sixspeed.

    I ran 119-120mph in a 3600lbs car in the 1/4 for many years with a T5. never blew it up. A good shifter to guarantee positive engagement, the right lube, and you should be good.

    (btw, that translates to over 525hp at the flywheel).


    Oh, and they didn't put T5's behind 350s for the same reasons you couldn't get a late 2nd gen with a manual in California. Emissions.

    Going by the other logic, do you think manual transmissions where not as strong while in California ??

    Jamie Passion is also coming out w/ a Muncie-based 5-speed.

    I'd look hard at it.

    Haha no. Was an '89 Firebird, T5, 6 puck ceramic clutch, 26x8.5" slicks one season, bfg drag radials the next.

    Got a ton of pix of the car if you want evidence. When I parted it out (bought a corvette) sold the trans to a kid who still is beating on it to this day. (this was maybe 2005).

    Sold the corvette and now I have another 2nd gen.

    I actually did the swap, if anyone in the thread still cares. I've been running the transmission in my car for over a year now behind abut a 300hp 355. Theres a few things about the swap that are kind of annoying, but I'm glad I did it, the overdrive is nice and I probably only spent 500 total on the swap. There's a lot of things that go into the swap.
    I started with a t-5 out of an 83 Camaro.
    Buy a starter, flywheel, clutch and pressure plate for the year camaro you get the tranny from, as flex plates from the autos and clutches and flywheels from the t-10 don't work.

    You need a driveshaft 3 inches shorter than the stock camaro one. You can (and I did) use a mid 90s two wheel drive jimmy or blazer driveshaft (I think mine was out of a 94) but you'll need to swap yokes. My driveshaft has a little bit of vibration issues so I recommend just getting your stock camaro one cut and balanced.

    The linkage is a little tricky. If anyone really wants to see it, its hard to explain without pics so I'll put them up later.

    Are you using a standard 4 speed console or automatic with the T5? Interested in hearing/seeing more about this setup.

    Currently I don't have a console. Just never got around to putting one in. I've put some thought into finding one with cup holders from a newer car and modifying it, but that's probably going to wait now that I'm building an L31 for the car.

    Old post I know, but since the thread got bumped, this needs corrected. MOST blocks are drilled for both starter bolt patterns and it has NOTHING to do with being a 305. The 168 tooth flywheel used the staggered starter pattern and the 153 tooth flywheel used the straight starter pattern, simple as that. There were 350's with the 153 flywheel as well as 305's with the 168 flywheel. Both styles were used as far back as the 60's.

    However, the 305 with T5 got a smaller body starter, in order to clear the bellhousing. The mounting bolts are also a little shorter than the older style, large body starter.

    It makes it really easy to just walk into AutoZone and order a clutch, flywheel, pressure plate and starter for an third gen manual. Everything bolts up perfectly in my experience. I am running a goodwrench 350 crate motor right now.
