Just looking for a opinion on wether I am doing this thing right. Swapping out a 6 cylinder stick to a 350 V-8 with a 700R4 behind it. I have a mock up block and a empty 700 case and have mounted it in the truck with the original front engine mounts to line up my side motor mounts. I have a 3 degree angle and seem to have plenty of clearance for a HEI . I did remove the original trans mount to make room for the 700 and going to the rear mount cross member set up. I did pull the engine forward about 1/2 inch to make sure I have enough clearance for HEI. After I have all things mounted should I put some kind of cross member back where original one was back by the spring mounts for more frame strength or will I be ok with out and is the 1/2 inch forward from original front mount location a big deal. Have not drilled holes for side mounts yet. Trans seems to have plenty of room between floor and case.

Hy Jhorrick, welcome, I think you should definitely reestablish the original engine rear crossmember in some configuration that will allow installation of the transmission of your choice. I don't think 1/2" forward location of the engine from stock location will cause any problems, good luck with your project.

I'm sure it would be an upgrade. You'll have a 350 and an automatic driveline that is still greatly limited in performance by the stock rear end, steering, suspension, and braking systems smile

The original crossmember in the bell housing area also stabilizes the rear spring mounting brackets. It's fairly simple to fabricate a bolt-in dropped crossmember from square tubing and steel plate that gives adequate clearance for the transmission and provides stability to the frame rails.

When I put a 350/700r4 in my 41, I went with cross members for both the engine and tranny.

Rear end is not stock and brakes have been upgraded to power disc/ drum with booster on firewall and installed Power steering with tilt column.
