i have a 90 454ss and i am planning on doing the 6.0 conversion with the 4l80e and was wondering if anyone could give me some info. i already know about the motor mounnt plates and the ac conversion. i have the 6.0 and the complete wiring harness but still looking for the trans. any ifo will help
You're sure going to make some purists cry, destroying a 454ss.
what do you need to know about the 80e? Is your harness and PCM already set up for the 80e?

What tranny do you have now?
If your getting rid of your drivetrain stuff lemme know. I might need it.
Get a LSX 454. Keep it a 454ss
That would be awesome! Cool idea Ricardo.

So what if you make a few cry. I love the trucks but the one i test drove made me sick to think of how slow it was. Even if you kept the 454 in it you'd still have to destroy it to make it run like it should lol. Good luck and keep us posted.Originally Posted by RedHeartbeat
David,
2003 GMC Sierra Denali, LQ4, AWD, AWS, 4.10, Wheatley 93 tune, LT headers, GMPP CAI, BBK 80mm TB, MSD wires, E3 plugs, 160* T-stat, Flowmonster DI/DO, cutouts. Working on 4.8 heads, just purchased Comp 228R cam, 918 Springs, TI retainers, 7.4 hardend pushrods,
i still have the stock th400 and a 700r but the 700 is blown and the 400 slips.
i posted the same thing on the 454ss club web site and no one answered back but ther are endless opertunities with these motors and not to mention emmissions are a bitch with a carburated motor witch i have in it now
if you wanna save money, get the th400 built, and get a 6.0. Thats my plan.
i want the overdrive evn though the 400 with the gearvender overdrive is awsome but i want to do something different. i may make some enemies doing this but there are no good or cost effective options with feul injection with the mark v big block
and i thoght the bell housing is deferent on the 6.0
