5 or 6 Speed in 66-67 Chevy II - Lateral-g Forums

**Sales@Dutchboys** · #1 01-24-2008, 06:16 PM

Im looking to do a 5 or 6 speed in my car soon, and I know that im going to need to cut the tunnel, which isnt a big deal. But i was wondering kits are you guys using? Ive been looking at Classic 5 speed and some other places.

Where have you have the best experience from?

Thanks,

Paul

I would do some sort of T56 kit if I was going to do a manual trans.

I missed this thread...

Paul, if you wanted to do it the easiest way, a Tremec TKO-600 would be the way to go. You can use all the stock clutch pedals and linkages for your car, as well as a stock GM bellhousing and use a standard mechanical speedometer.

I switched mine to a TKO 600 using the stock components and it works excellent. Mine came from Classic Chevy 5 Speed, they were very helpful with any questions I had before and during the swap - couldn't be happier.

Yeah, for a small block, the TKO-600 is a much easier swap. I'm using the road race version with the .82 OD 5th and have no complaints. They are also stronger and lighter than a T56, though you do give up the .5 OD 6th. Some people have to have that gear, others find it not so useful.

We put a TKO-600 in my Dad's '67 Chevy II about 5 years ago. His car is pretty well stock. It bolted in right in place of the 4-speed - we did have to modify the trans tunnel. His car had the original 4-speed trans tunnel. At the time, noone made an offset shifter to come through the factory location, so we had to mod it more to make the shifter hole location in the center. I think he bought the cross-member from National Nostalgic Nova. I don't even know if CC 5-speed was around back then, if so, we didn't know about them.

Are you going to go with a hydraulic throwout bearing setup? Dad's car still has the stock subframe, so we were able to use the stock Chevy II z-bar setup for the clutch linkage. I don't know if Alston's has provisions for this or not. I'm sure you could make the stock pedals and linkage work though.

Hopefully that rambling made some sense.

One more comment, depending on how your car is geared, the standard 3.27 low gear is REALLY LOW. I would consider the 2.95 first gear.
