1. WHY not go with an Olds 350? or 403? 403's are also small blocks and bolt right in... and are cooler than an Olds/Chevy hybrid... and tire frying TORQUEY!

2. If you must go Chevy, the 200-4R w/ OD from an '86 & newer Monte or Pontiac GP goes right in with the same driveshaft... as does the 3-speed TH350 or TH 200 from an '85 and earlier...

I heard you have to chop the drive shaft 3" for the 200R4
