Which one is the best and the cheapest for a 94 blazer\350 motor...thanks!...3.42 rearend..

 

It all depends on what you are trying to achieve. Do you want more low end or more top end? If you want more low end power, get a supercharger. If you want more top end power, get a turbo.

I can't quote you a price on a turbo right now. But the supercharger will probably run you around $2600 to $2700 and then you would need to pay for shipping. The trusted supercharger around this forum is a Wynjammer.

I'll get back to this later this eve after work & a few beer. In the meantime search the forum! There are a lot of threads & posts about both & how they compare.

 

Supercharger is bolt on, turbo requires a bit of fab. Just something to think about aside from the cost.
