The parts that are California CARB legal won't give you the horsepower /performance your looking for------The parts that you need to make a 350/383? aren't even sold in California--the aftermarket companies won't/can't even ship those parts to California.

The Montes were good looking cars and it would make a nice cruiser-------but even though I have a machine /race engine shop and do this type builds, for your stated budjet/location/etc-I'd recommend using the engine /trans/ecm out of a late model Camaro with the complete accessory package for alt/ac/etc---why just the accessory drive package and current Freon ac package will cost you around $3000 for your 350------
