TKO 600 or T-56 ?

I was going to save a couple bucks and go TKO and opted for the close ratio T56 Mag.........3+ years later I am so glad I didn't make the mistake. The T56 makes the car. 26.5" tire, 3:73's, 2,100 rpm in 5th = 60 mph, 2,000 in 6th = 70 mph +/- 1 mph GPS mph's.

This is interesting. I just called D&D back and spoke with Don. I was concerned with the need to modify the trans tunnel. He informed me that while its true the T56 is heavier, it has a round top compared to the TKO flat top, and that it will indeed fit a first gen with no tunnel mods.

Personally I do not want to mod my trans tunnel. Does it depend on the engine mounts used?

Has anyone used the Holley system (engine mounts, crossmember, etc.) with a T56 or T56 Magnum and not cut the tunnel?
