LS7 and T56 Hey. I have searched the site and did not find my answer so here I go. I have an LS7 left over from a project that I sold. It has TSP ported heads, MAST Motorsports cam and spring kit, and a FAST 102mm intake and cable driven throttle body. I want to use it now in my 2001 SLP SS. I have already had my T56 upgraded with metal shift forks, upgraded gears, and other items. I also have a complete McLoed RTS twin disc clutch kit with flywheel Nib for the LS7 What else would I need to do or buy to get this transmission to work with the 600hp LS7? This is a 100% street car. I have to finish up with the car that I’m working on right now and then I will be collecting on stuff for this one. The car only has 62,000 miles on it now so I have time. I also plan on getting the Dana S60 rear end. I don’t think my .390 year 10 bolt will hold up with 19x12 Grand Sport wheels and the LS7 power. Thanks.

Maybe the correct pilot bushing. My trans has everything but the Viper main shaft. The car should make close to 540 or so RWHP so I don’t think I will need much more. It would be nice if the rear end would work. That would really speed things up. I have thought about just converting it to wet sump and bolting it in. I have long tube headers and big y-pipe and SLP CME 3” cat back exhaust. Those items would cost me a chunk of power.

Thanks. I was very happy with the end product. She made the covers just like I drew them up. It was a pain to install but well worth it. I have learned from past projects that it only cost a little more but the extra effort pays off. I have also collected up on all of the items that I need to convert my LS7 to a wet sump engine. I just need to find a machine shop to swap out my reluctor wheel. As for the transmission, I am saving up for the T56 F right now. I am going to keep the original engine and transmission together. I might put that in my father in law’s ‘65 El Camino.

Hey. Thanks for the response. As it worked out I have almost enough left over from selling my’70 Camaro to get the T56 F. That way I can keep my original drivetrain together and save it for later.

I have an RPM Level 5 T56 and my main gripe with it is the dual synchros. The 1-2 upshift is getting more difficult at high rpm. Back in those days I didn't know enough to ask for triple synchros. But times have changed and building a T56 makes no sense IMO ever since the release of the Magnum F at $3400. That was a game changer.

That’s what I went with, the Magnum F. Very slick shifting transmission. If you have the money for your project definitely sell your old 6 speed and get the Magnum F.
