Selling a pair, about 150 hrs since rebuilt, I'm currently rebuilding the heads new valves, Inconel exhaust, springs, retainers and valve job, these are GM performance heads, I had to tear one completely down because a valve came in contact with the piston, head was cleaned up, repaired and CC'd . These are stock rotating assemblies, kellogg cranks, dimple rods and je-700 pistons and custom Isky cams, they were dyno'd at 525-530, Id like to sell as is, would consider trades for complete 871-1071 blowers, intakes, carbs, chillers, SSM lll 3a's and gimbles

Open to cash offers, buyer pays shipping

These came out of my buddies TG, he replaced them with 572's

These are complete from carb to pan, no accessories + aluminum water pumps

Something wrong with this site I cant edit my own post.............the carbs are 850's same part # as the HP500 engines

Forwarded the link to a friend. Any chance you'd split them Ken?

I may, need to let the ad run a bit,

thanks man

I believe stock HP500 carbs are 830 CFM.....

You mean someone on this board was wrong in their info given to me, Im shocked LOL

thanks for the input

Just in time for Christmas

The stock HP500 carbs are Holley #9022 and 800cfm.

Griffs correct just looked at it .... 9022....800cfm....these intakes are deff. marine, they have a brass insert in the thermo housing area and are 8 bolt instead of 6

What was the price on these motors
