All blazers are 4.3 equipped (except for the earlier which also had a 2.8 i believe). Yeah I wouldt waste any money on the 4.3. If you wantr speed to a v8 swap. I helped a buddy supercharge his 01 blazer and it ran a best of 14.91@91 or something like that. It was a huge dissapointment. He too has learned and has a small block getting ready to go into his 97 s-10 now. Good luck!
