This is not a restoration motor, but an excellent street/strip engine if you don't care about date coding and broach marks. I built this motor for a Chevy High Performance magazine article (I'll have to remember exactly which month it ran) and have never had time to do anything with it.
Specs: 1978 445-casting 2-bolt block, line honed, ARP studded mains Resized 3/8" 'truck' rods with ARP waveloc bolts, floating pins, shot peened Brand new GM steel crank, std/std, 6223 forging Federal Mogul Competition series bearings +0.030" SRP medium-dome pistons, JE file-fit rings Fully balanced assembly 9.75:1 compression Merlin oval port iron heads Howard solid cam (245/252 @ 0.050", .587/.578, 110LSA) Howard 1.7 billet roller rockers Howard custom length hardened pushrods Howard EDM-drilled "direct lube" lifters Merlin cast valve covers World Products dual plane intake (looks like a GM 063 copy) BG Speed Demon 750 mech-secondary carb Milodon HV oil pump and 8-qt Chevelle pan All ARP fasteners PowerBond SFI balancer (Australian made) Flexplate Stock distributor with Unilite conversion Dyno time only Made 501 hp @ 6300rpm, 510 lb-ft @ 4000 rpm. Torque curve is nice and flat--it made 468 lb-ft @ 3000 rpm. I'm only considering selling it because I haven't touched the thing since I built it. Looking for $5000 for everything. Thanks for the ad, Tony |
