Swap to L31 350
Ok...so here's the plan. Taking the existing 305 TBI out and swapping it for my Vortec L31. Plan is to upgrade the cam, springs, and rockers for something bigger. Has anyone done this before?

Many people have done that swap I would use the search function and google. There is a massive wealth of info out there.
