Who's running a PG behind a small block?
You will be looking to spend close to a grand to install a powerglide tranny if you are intending to do all the fab work.The adapter plate can be a couple of hundred bucks,a new drive shaft as it will be about a foot longer because the PG is about a foot shorter than a 727,and the fab work to make the new tranny mount close to the front or adapt a bracket onto the origanal mount.Do decide on which tranny to use,a straight 6 version or a V8 model,same bolt pattern but different gear ratio,s.If you do intend to install one,spare no expense on a rebuild and by the best parts on the market,as the tranny was made for a couple of hundred HP and not pony power of 400hp and more.Many a drag car have them and run well,but fatiuge is a problem,and when they go,they go with a bang and parts fly,mrmopartech
