Going from a 4.3L to a 7.4L ??
« on: June 25, 2006, 12:12:00 pm »
Hi

I'm new to this forum. I have a 1986 Chevy C-10 Short Bed pick-up, 4.3L, 4 speed manual, that I have owned since 1989. The motor is worn out know and the trany needs a clutch. Bought a rebuilt 1982 454 V-8 and a turbo 400 transmission yesterday that I'm going to install in my truck.

My question is: Do I need to buy new motor mounts for the trucks crossmember? Or will the 454 bolt in where the 4.3L was?

I could be wrong, but I believe the mounts will work, I haven't really looked at V6 mounts for this year of truck. Someone correct me here......I am sure you will have to move tranny crossmember for TH400 to work.
