Hey, guys, First I wanna say TGO Rocks! i just completed a carb'ed V6 to L98 swap thanks to this site! Anyhoo, I was just kinda wondering what kind of power I can look for (Ball park figure would be great!) with the setup I got now.... I'm runnin a Melling torque cam (Lift .420/.443 Duration @ .050" 204¯/214) with mostly stock runnin gear, except for a ported plenum, iron 1.94 heads from an old (OLD) chevy truck, homemade ram air, full header and exhaust system and a 3.42 rear Also I was wondering if a t-5 I pulled from an 89 chevy 3/4 ton would stand up to the 350? Thanks Guys!

Lucky if it breaks 300hp/320tq...at the crank...and the T5 trans should have no problems standing up to it.

A truck T-5 (you sure it's V8 truck?) would have the shifter coming out too far forward for your F-Body...you'd want one fron another car or have to replace some stuff...

Reason I ask is if it's a V8 truck, I didn't think the trucks got a T-5 unless they were smaller trucks w/V6's...i know you mentioned 3/4ton...that'd almost lead me to think it'd be a regular truck tranny...i/e with compound low style...anyway just curious about that.


Do you have a pic of the tranny?

only trucks that got those were Diesel trucks

No full size trucks got a T-5. Only S-10s and S-15s got one with the 2.5 and 2.8. The 4.3 S trucks had the NV 3500 which is probably what you have if it is from a 3/4 ton full size. Could even be an NV 4500 in which case the trans would never fit the tunnel of a Camaro(they are quite tall). I agree with the guy above, the shifter would be back too far. But it would take the abuse well if it would fit

Thanks Guys, I'll try to get some pic's of the Tranny today, hopefully posted by this evening. it does look awfully tall compared to the 700, but hopefully

Anything I can do to help! Oh yeah, and "You're Welcome"

Well, The Digital camera took a crap today, so no pics, but i did get the casting numbers, don't know if that will do any good or not. Any tech wizards who can tell me what they identify the Tranny as will be bowed down to profusely

Pt # GM8672304 (main case)
Pt# GM8672305 (bell housing)

I also looked at some T-5's on ebay, and the tranny I have is different, it has a taller midsection and has what look like structural ribbing on the main case..... Tranny's are outta my league, so I'm not really sure what this is.

Sounds like an NV 3500 or 4500. It is steel or aluminum?

it's all aluminum, after doing some research it looks like its an NV3500, so I guess it won't be going in the TA after all, unless there's some way to modify the shifter. ahh well, time to make a trip to the junkyard

then it is a 3500 because the 4500 had a cast iron case and are really tall. Yeah, sorry, won't fit too well in your F-body. Good luck in your search for a T-5/T-56.

Thanks for the help, Chev, and to everyone else too!

Any Time!
