Hot Rod Dad, make it easy on yourself, try Classic Parts (aka
Chevy Duty) & get the V8 adaptor cross member (Pt # 79-405
for around $55) & V8 motor pads (Pt# 79-015 for $20 ea.) & they also have a std. trans (Pt# 79-505) crossmember that
works well for the AD's for around $45!
They & Brothers have a great tech line of people to give you some good advice / help !
Hope this helps, I went the 350 crate route w/400 turbo,
you can see it in Classic Truck mag. (pg. 86 / Jan 2007 new
issue !)
