engine mounts

I bought a 85 suburban for the 454 and 400 tranny to go into my 69 nova. I looked and the mounts look different from each other. The ones for the 454 were wider than the frame mounted one in the nova. Where do I find mounts that will work?

Auto parts store. If your Nova had a v-8 in it originally. The frame mounts will work with corresponding 69 Nova small block v-8 motor mounts. The small block mounts will bolt to the big block engine. With the correct oil pan and non-power brakes. Pull the heater box and flip the heater core so the tubes come out on the fender side. Then re-drill the heater box hose outlets.. The big block will bolt into the 69 chassis. Sometimes you will need the GM. 1/4" spacers under the engine mounts. You will need a BIG radiator. Also a 400 turbo crossmember. The 400 crossmember is made from tubing and the 350/standard member is a stamped box type. Holes are already in the frame rails for either crossmember.

As I stated this will work. I have done several. The Exact, correct, way is to. Purchase the correct big block frame mounts (wider/lower and offset the motor to the right, this gives clearance to power brake booster/valve cover). The correct big block motor mount is also wider and stronger. BUT the small block stuff will work if you are on a budget

Im putting a big block in my nova and I bought some frame pads from NPD for a 68 camaro ( I would have used the 69 style as it is the same for the nova but I had these solid mounts laying around) for 60 bucks. I didnt know about flipping the heater core though. I was going to get the big block one or just block it off as I havenet used it in 2 years becuase the core leaks.
