Ive never had a blazer but I did have a S10 Xtreme with a 4.3V6 and a 5 speed in it and it was alot of fun. Had it for 2 years before hitting a deer with it and thus totaling it. I drove the crap outta that thing from burnouts in 1st to 2nd and chirping em in 3rd it was alot of fun and I surprised alot of people on the streets with it
