Well ive been contemplating for a while now, whether i should keep my 86 blazer 350, and try to make some power out of it, or if i should buy a new crate engine. I know the blazers were not known for their horsepower....but what about supercharging it? I want something with around 350 horsepower. Id have to switch over to TPI as well considering im running TBI now. Do you think i could get the 86 blazer engine with 50,000 miles on it to 350 horsepower with a supercharger....or should i just look into crate engine, or building up this 350 naturally??? Well thanks for any info guys.
