Please Contact Alex Hays at 7349266067 if you're a serious potential buyer, no tires kickers if you low ball me Ill tell you to go eat a dick
$35000 obo will throw in a new block at $35000

Motor will need a Hone, a set of .937 key way lifters and pistons to match current bore in the block, or use the new pistons in your block/new block and hone your block to fit them. I can get you a new big M block and used or new lifters if buyer would like.
It is currently disassembled and at Mid South Racing Engines in Tennessee. Will be picking it all up still disassembled in the next few weeks. Or Buyer can pay to have it assembled by Ian Landies at Mid South Racing Engines.

Motor was originally built and upgraded several times by Uratchko Racing Engines. Conventional headed 588” BBC has been 4.693 @ 153.81 @2905lbs (efi), 4.697 @ 151.65 @ 2915lbs (efi) and 4.691 @ 144 @2850lbs (carb) All passes made on a 275 drag radial. Current world record holding engine for an Naturally Aspirated drag radial combo. Would make a stellar nitrous combo with a different pistons design.

Motor was never on an engine dyno after EFI swap but estimated to make 1420 to 1440 at the crank based off ET and weights ran at various track and various conditions. It was put on a chassis dyno with 2 pulls to 9000 made 1180 rwhp at 9000rpm with a 8300rpm loose stall converter. With a 2.800” carb and before cam changes the motor made 1395hp and 926 ft lbs on the first pull to 8500 rpm on bob book racing engines dyno; before dyno had issues and we were not able to run it to max rpm motor peaks at 9000.
