Pre-Vortec power difference?

Thanks Sunlit. Probably the best advice. Don't really care if it has Autotrac or not. What year started the solid front axle again?

those disappeared with the k5 blazers in '91 tho it may have been earlier. i think the dana 44 were no longer used by about 1977. the nineties were just about all IFS. iwould have to research to double check tho.

Ya I was kidding. 1987 last year for Pickups, 91 last year for Blazers.
