thanks showme49 for the heads up on the air intake. I'll have to borrow the wife's suburban

and see what the clearances are. I think I have enough room to use the mechanical fan but I need to check that also.
I'm pretty sure the F-body exhaust will work but I need to track down the ones locally.
Two questions: How many degrees of tilt did you use (one site says 4 degrees for the ls series, my mechanic guru says 3 is ok, not a big deal but just curious). My 4L60E fits pretty well with a small radius out of the firewall, but what trans cross member did you use? The S10 will not work without some major cutting. The frame rails open up and taper in my setup position and I'm sure yours do also. Will probably wind up using the 88-98 full sized pu cross member, just have to find one at the local yard.
