Quick question guys. My buddy has a 305 vortech out of a 96 1500. He wants to build it up and we don't know what a 305 block is capable of. I've played around in Desktop Dyno (with my limited knowledge) and we can get some nice numbers. The biggie question is what is the block capable of? He's got a 400 but it's about a 24 hour roundtrip away plus it needs rebuilt. Is it worth trying to build the 305 or just suck it up and go get the 400? He wants a street machine, this isnt a 4wd truck. thanks guys.
