I have a 455 short block that needs rings and bearings and its good to go. It have 30 over forged pistons and they are eyebrowed. would be like a 10 to one piston. the crank is std/std It has a new SFI flex plate. I the block has the larger oil hole and been sguared and decked. i might have a set of good stock 70 heads for this mtr as well. The block should be a 70. I will double check the numbers. the heads are 70s. I also a have a old KB 107 cam I might throw in it if you want it all as well as maybe a front cover and some rockers. i would like $840 for it all or call and make me a offer. I am having trouble with my camera and posting so give me some time if you want pics. or call 209 535 6968 leave a message i will get back to you Thanks Doug
