I am putting a BBC into my 79 El Camino. Since Chevy did not offer this engine in the 79 G-body, how should I go about selecting motor mount part #'s? Any help is greatly appreciated!
The small block motor mounts bolt right up to the big block. I put a 454 in my 80 Lemans. You will require hooker super comp headers and have to adapt the tranny cross member for dual exhaust. plus the stock 250 tranny will not hold up. a 350 tranny will bolt right in as well. you will have to use the 250 rubber tranny mount though. It only has one bolt instead of 2. visit my website. All info you need should be there. http://members.shaw.ca/g.body.building
I have heard that the small block mounts position the engine higher than big block mounts. Is this true? Also do big block mounts offset the engine slightly left for heater / air conditioner clearance?
Yes you`ll need big block mounts. But you should be able to locate big block mounts are your local parts store for a passenger car, all they`ll have to do is dig into there computer. the bb mounts sit lower and are offset.
The big block is 2 inches taller all by itself. My engine sits to the left. The stock 305 may have as well. But I had no problems installing the headers. Check out http://www.maliburacing.com He did the same thing I did with no problems. Both of our cars run 11s. My vette motor sits to the left as well. It was made that way for the emergency brake cable to run down the driveshaft tunnel. I never gave it a second thought.
