I only want to have spent 10k all up on car and my conversion (already have suspension, brakes, and everything but engine conversion sorted), so only have about 5k to spend on engine conversion but I got the engine for free, box setup is a bit under 3k for my conversion, $1000 max for cage, diff should be about $300, $250 for paint and rust repairs, and then the random stuff that is involved in any conversion, so will be very tight but should be able to squeeze it in there.
