The rebuild consisted ofall new pistons, cam, lifters, valves, valve guides, valve springs, fuel pump,oil pump, distributor (dual points), rings and main/rod bearings. The rebuiltitems were rods, cylinders,crankshaft, harmonic balancer, heads.Other new items were Nissan Sentra starter and ring gear, William Wynne prop hub& lightweight oil pan, CNC cut top cover.Once I started assembly it took me approx 3 weeks to have the engine on the teststand and running.So far I have 13 hours on it.

Tom,I have a minimum in my Corvair. I paid about $40.00 for it. I bought forged pistons,about $350.00, had crank ground and pistons honed, about $150.00, Newrings, from Clark's, you can call them at 413-625-9776 and order their catalogand check all their prices. New oil pump, from Clark's, Exhaust valves, valvesprings & valve seals , all from Clark's, larger oil cooler from Clark's, NewJohn Deere alternator and regulator, $345.00, new rod bolts, do not rememberwhat they were but not from Clark's, welded up the engine mount my self, andmost importantly, William Wynn's Corvair overhaul manual as well as Richard Finksbook on Corvair engines. I can not give you a total, as I have done it piecemealand I promise you, it is a lot less than a Lycoming or Continental. Oh yes, bought the prop hub and puck from William Wynn. You can go to his weblink and check his prices. Bearings for the crank, about $350.00. J.C. Whitneywould have been less but I had the man who did the crank and cylinders orderthem so I would be sure to get the correct size. Oh yes, a new OT-10 cam shaftfrom Clark's. Ordered 6061-T6 1/8 inch piece of aluminum from Aircraft Spruceto make the top cover for the engine. New valve rockers from Corvair underground,I think. You can take the Clark's catalog and price list and piece together about what youcan spend. I spent a lot less than some but probably about average for most.Alex SloanFlorence, Alabama. ----- Original Message -----

that's too large for a Corvair if you want to take advantage of the full horsepower. at 2,000 rpm you're getting maybe 55hp at most. You need to spin it upto at least 2600 static. It will unload to about 2800 or so on the rolloutgiving you almost the full 100hp.You'll need something like a 62x34 through a 66x29. I have a 66x29 on mine andit gets 2700 static.DJ----- Original Message -----

Sorry just downloaded my messages; I should have also said that I amrunning a Lycoming 0-235. When my test pilot did his test he got 2000RPMstatic and unloaded to 2100RPM in the take of roll, he did a dive downto the runway and she unloaded to 2200RPM at a max of 75kts, cruised at55kts 2100RPM. I agree that I have to much prop, I just got back home from the previousowner, he gave me one of the previous props that was on the plane a GSC72" dia, the original owner no longer has any of the props he had testedon her.Just some history, the plane did a nose over on landing in about 1984and had not flown since, she has been recovered and the motor has beenmajored with all the mandatory mods done. The 0-235 has of date 10Hrssince major, airframe has 1.3Hrs since major.>Norman, Most of the Continental A65's that I've seen, including mine, has a72 X 42 wooden prop.
