i have 89 blazer with 4.3 tbi.... the motor i have is a 5.7 with 2 cylinders less. so i was wondering if i could buy a lt4 hotcam for this motorl but u know it would have to be shorter... does anyone know who would make this cam?????

 

Find the spec's for the HOTCAM. (do a search on this site to do that), them go to COMPCAMS.COM and find your engine. It will pull up all the cams they have available. Do a similar search on other CAM makers and compare the specs if thats what you want to matchup on.
You would actually be better off consulting with a cam maker on what you need 'cause there's more to it than just slapping in a cam to consider.
