ive been looking for a 454 for a couple weeks, ever since my 350 has been acting REALLY tired. i find this on craigslist in detroit. its a 454 GM test motor. its the only 454 that i have seen with the coil on plug and a drive by wire. it has a block heater and a wierd balancer, and 8 quart oil pan (that i just hope clears the front diff, looks like it'll be a tight fit). its missing most of the head bolts(have 12), only have 2 valve cover bolts, 2 upper pletnium bolts, and 2 or 3 intake bolts. it doesn't have a partial vin on the block, just the numbers that you see written on the valve covers. the big reason i bought it is its preaty much a new block, heads and its a factory roller cam. i know it has a broken piston skirt and atleast 1 broken ring (only pulled one piston out). im going to rebuild it and squeeze some more power out of it. id like to keep the vortec FI, but i don't have a harness or a computer. i also will have to put a distributor back in it, unless i can find a 8.1L harness, computer and the rest of the drive by wire setup. i picked this up for $500 saturday i went to a racecar swap meet to sell some of my small block stuff. i get to walking around and i find this. picked it up for $75 im going to clean it up and rebuild it. i also traded one of my 4 bolt 350 blocks for a set of brandnew headers for a chevy truck with a BBC.
