I have a 52 Chevy Sports Coupe. The 1954 235 died and I'm ready to ditch the old six and go with something more uptodate. I have open drive line (Ford 9 inch), power disk brakes, hydraulic clutch with a stock front suspension. This is a daily driver for my son, we were long haulers in the 2004 Hot Rod Power Tour. Thinking of getting a complete 5.3 Gen III engine with trans and electronics from a truck or SUV. What problems will I have in the physical mounting of the engine. I've read that the oil pan can present clearance problems in general. Want to use the trans from the donor car as my T-5 came out of a 2.8 V6. I sectioned the trans cross member to mount T-5, could possibly adapt it's mount for the new trans. Alternate swaps, 350 or even a 4.3. Gas milage and reliability bigger goal than spinning tires, though son came off Power Tour with serious case of V8 envy.
