Well if you already have a 4v short block then maybe but it still seems like a hassle. It would be pretty easy to grab a 97 cobra engine. Prep the block and the crank, buy rods and pistons. Work over the heads and shorten the intake runners and boom capable of a 1000hp. Plus then you already have the rest of the components for the swap. Oh and you'll have the almighty Teksid block.

 

they say to go with the b heads and a blower and the mark 8 comes with 295 hp and the cobra 305 cheap route is to buy my pi stuff lol so i can go 4v lol im gonna go with the mrk8 and cobra intake they said that the b heads flow tomuch for stock trim so get a blower or cams
