The engine in my 89 TBI Blazer is getting pretty tired and I'm planning on replacing it soon. I don't want to mess around with modding any of the stock TBI stuff as it works fine, but want to get the most out of it. So, here is my question...what would be the highest HP GM crate engine the stock TBI would work properly on without any mods to the TBI? Am I correct in assuming the 200HP/300TQ 350cid? Thanks.
