TKO or T56?

[mstennes]

Here's my delima I'm almost ready to start tearing out my old 383 and 2004R and I picked up a a LS7 and cant decide which way to go TKO 5 speed or a T56 6 speed, what is the best setup for this engine? Its going in my 69 Camaro if that helps.
Thanks,
Mike

Since no one else wants to play, let me give you my 2 cents' worth: I say TKO 600 5-spd, that's what I went with for my big block Trans Am.
From research I've done it seems that the TKO is a bulletproof tranny and the "downside" of having 1 less gear is really not an issue, IMHO, unless you plan on running 4:50+ rear gears or plan on going 200 mph.

P.S. To be fair, I can't vouch for either one personally yet, I am waiting for my driveshaft to get here to try out my TKO, I am just going off of what I have read in other reviews.

I had a tko in my in last 69. The thing work great w/ no problems. I used a turbo 400 crossmember & just cut the mount off the back and welded it to the front of the crossmember.The 93 LT1 was mounted in the stock location and the mount worked as if GM had wanted it too. The T56 you will have to rise your trans tunnel up some to make it fit.And shorten the drive .W/ the TKO my stock drive shaft worked. There both great trans But install what will really make you happy. Good luck.

The reason I wondering is I have a T56 out of a Viper I bought off a friend a while back but it would be nothing to sell it and go with a TKO, I have a set of 4.56s that were for another project and I just kinda thought 6 speeds, 4.56's that could be fun????? I dont care about how fast it will go, anything over 140 in a convertable (anything over a 100) gets kinda interesting. So its TKO 500/600 than? What is the optimum rear ratio with a 500 horse LS7 and a T56? How about a TKO?
Thanks!

My car had 4:11s at 70 mph 2200rpm. I had 315/35/17 rear tire 26.5 inches tall.If you have a T56 use it. good luck.Scott

Is that a stock T56 that you are running at 2200 rpm's at 70 mph, cause your tire size,trans, and gears are the same as my 70 Chevelle's got, I'm just waiting on the T56 to get back from the shop. I was wondering what I would be turning at 70mph.
