TKO 600 vs T56

[DRJDVM's '69]

I posted this over at Pro-touring.com but have had no replies at all...

Its time to dump the M20 since it sucks on the freeway !!! I'm trying to decide on a T56 or TKO 600. The motor I have puts out around 450 HP but I'm planning on building a supercharged 406 ( or maybe even a 427 sbc) this year, so I am planning on pushing the 600 TQ barrier then. The car will be 99 % street driven

I dont want to do much as far as tunnel mods or shifter opening cutting etc.... Overall cost is major factor too.

My concern with the TKO is that the 0.64 will drop the RPM too much and the car wont like cruising at 2000 RPM and the 0.82, wont drop it enough to make it worth the $$ (my current motor seems to stumble some when I try to cruise at a lower speed and 2100 RPM range, but not sure about the planned motor).

The TKO 600 gives me more TQ tolerance at an "off the shelf level" and the cost is lower...

The T56 gives me both the 0.80 and 0.62, so I have more options depending on the situation I'm driving at....

My concern with the T56 is the cost...... more to build it to handle that kind of TQ, and more stuff to install it. I'm also worried about having to do more tunnel. and shifter opening mods to get it to fit...

So....... am suggestions ????
