What are the best small block to big block conversion mounts?

Some guys have recommended to me that even on a street swap I use a motor plate. On a B/RB this is relatively simple because you can just shave off the rear of the pump housing by the thickness of the plate, and still use the existing pulley setup. This frees up a fair amount of area for exhaust, etc

I agree 100%. This is an original 383 4-speed GTS so no welding or cutting. Streeeeeeeet car lol.

I have a car with an tunnel ram/ Indy -13 w/ Ti valves and a Lenco...and a motor plate. It has glass doors and lexan.

My other motor plate app is a 511" (1000+ on n20) with a G-Force GF5r 5 speed, 2x beadlocks etc. More of a strip-street car.

The GTS is more of a run to the hardware store and stop at the local track for grudge night on the way home kind of machine. Motor plates are shiny...and for race cars lol.
