Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
For $3k you could pick up a low k L67 motor with the supercharger all bolt on loom and probably the box as well. Far better then boosting an L34 donk. I picked up one with reasonable ks for $1500 and put it in my VB. A set of extractors, 10lb pulley, high ratio rockers and you are away. Cheap power and lots of low down torque.
The guy paid 3K for a full rebuild which would be better than any L67 out there with 100-200,000K's on it.
as the guy said hes a beginner.
as the other guy said he done it all himself.
l67 would be the way to go for him for forced induction
