Early thick casting 360 block with Icon forged stroker kit. 10:1 compression, rings gapped for up to 200 shot of nitrous. Rotating assembly was fully balanced with Fluidamper SFI balancer. Block was line honed and the .030 bore job was done with plates. Zero decked block. Hughes EDM oil through solid lifters. Cloyes Race Billet double roller timing set with tensioner. Speedmaster CNC heads that have been worked over a little extra with 3 angle stainless valves, PAC Racing 1900 series dual valve springs and new 273 style adjustable rockers. Smith Brothers .120" wall 5/16" pushrods. Hughes Engines solid flat tappet cam STL4650AS .576" Intake .588" exhaust Duration @.050 246 In 250 Ex 108 lobe separation. Flow Kooler water pump with 180* thermostat, Melling high volume oil pump, ARP head bolts and main studs, Edelbrock Victor 340 intake that has been fully ported. Mallory Unilite distributor with Mallory ceramic boot wires. Currently has a truck style oil pan on it with a scraper bar but also have a new in box Kevco pan and pickup for A-body that is negotiable. Engine has about 200 miles on it and has been dynoed at 500.6HP@6400 and 501.62 Ft lb @4500 (Graph shown has better average power but slightly lower peak numbers) The down side is I got chassis twist the one time I took the truck to the drag strip and the rearward ears for the engine mounts are broken. Talked with a machine shop who said they could repair back to factory strength but block has to be taken all the way down to do it. 750 Race Brawler Carb and Doug's A-body headers are negotiable as well as a nitrous kit with 3 jet sets and 2 bottles. I have more than $8.5k into this engine but would cost significantly more than that to have a shop build its like. Can come hear it run in truck before I pull it soon at which point and I'll either tear it down to get the ears repaired and increase price accordingly, or just install a motor plate and keep it. No I'm not going to drop the price a ridiculous amount so don't bother insulting me with a low ball offer. Only looking to sell as I might be switching out to a big block.
