What plate would this be? I tried asking what kind of adaptation I would need for the tranny, but I was told none, so can someone fill me in here. Thanks.

I think what he is refering to is the B&M adapter for a TH350 into a third gen. What you are needing to do (if I have this right) is adapet a 700R4 from a V6 to a V8 and I don't think one is made for that. I beleive you will have to get another tranny that will fit a V8. (If I remember corectley some v6's have a different bellhousing pattern then the other v6's and v8's)

not sure about the adapter plate you need arron, but both jegs and summit sell adapter plates might want to call them, i currently have a chevy motor to a pontiac tras in my 69 gmc truck, now i just need to do the opposite and go from pontiac motor to chevy trans,
