Basically, the 8.1 isn't worth the effort of the swap.
its a TBI454, there are NO performace parts AT ALL. it has only 230HP, thats just not going to work. to get the kind of power i want, it would be cheaper and WAY eisier to just swap the engine and be done. i have allready priced all of the parts. its just not worth keeping anything other then the block at most, but it would be cheaper to buy a used vortec engine, and rebuild it, then buy all of the parts to convert it to a vortec.
