I may have a line on another Blazer. It is an 89, but he has put an older 350 in it with a carb. He says he may have all of the TBI stuff, ie. heads, intake, TBI, harness, ECM. My questions are: 1. Will the newer style heads fit on the old style blocks? 2. Will the newer style intake fit on the older style heads? He has the old motor (original) bored out .30 over that will go with the deal. 3. Will the stock TBI work with a mildly built .30 over block? If it can be juiced up still running the stock TBI or needs to be to make up for the .30 over bore. 4. What mods can I do without going to deep in my pockets. The end state is to put the TBI back on the motor in it or rebuilb the original motor that has allready been bored .30 over. Mild, but not too wild !! <font color=red>BigBurb <font color=purple>IF YOU'RE SCARED, SAY YOU'RE SCARED !!
