Ken-
Go for the WC T-5 tranny but try to find one from a 1980-83 Camero Z-28. These are a little stronger than the V-6 T-5's and mine bolted up to the stock 292 perfectly. I used an available 230 10.5" flywheel, re-surfaced, and bolt holes opened up to 1/2". A stock 292 flywheel should be fine as they range from 10"-11" depending which vehicle it came out of.
Clutch linkage was a snap with no modifications at all on my '40 Coupe. I also used a stock Aluminum bellhousing from any GM small block (mine was from a '63 Vette) and I installed a new CenterForce clutch. I have over 4500 miles of in-town, freeway, and stoplight thrashing on the the drive train with no noticable change. The WC T-5 was not intended for Drag Racing but for Street use, it should last with some common sense.
I use a rebuilt 3:55 Posi 10-bolt rear from a '68 Nova (8.2") and with the 30" tall rear tires, I tach approx 2200 RPM's at 70 MPH! The '83 T-5 has a 2.97 first gear so stoplight starts are brisk but short and the OD is 0.64 which is nice for the highway.
The Tremec is a fine transmission but at what cost? You can find a WC T-5 and have it rebuilt for less than the cost a new Tremec.
Good Luck and let us know how it works out.
