Greetings all,I am going to pick up some Corvair engines this weekend, (my Christmas present!)and after checking the #s I found that one is a pre '65, and I don't recallthe exact hp, but it is less than 110 hp. Will this have any parts usable on the110? I'm sure something on this subject is archived , but so far all I couldfind was the difference in cranks (pre 65's are weaker?) and bore size. I amalso wondering if I need to get some sort of bell housing...seems like I rememberreading something about needing one for something, but I don't recall thespecifics. I do plan on getting William's conversion manual, but I stumbled ontothese engines and want to nab 'em before they're gone! Thanks in advance...Jon Jones in southeast Missouri...still trying to save up for plans & spruce withoutupsetting the wife too much.________________________________________________________________________________

First, the disclaimer (sorry Gene; I just had to do that ;o)- Jon wrote:>after checking the #s I found that one is a pre '65, and>I don't recall the exact hp, but it is less than 110 hp.It is a nominal 95 HP. Still plenty good for the Pietenpol, but if you're going to go to the effort of converting a Corvair, it's the same cost and labor to convert the 110 HP as it is the 95 HP (some might say it's even more, since parts for the 95 HP are less common).>Will this have any parts usable on the 110?Yes, very many. If the engine is complete, by all means pick it up!>so far all I could find was the difference in cranks (pre 65's are weaker?)The crank on the 110 HP has a longer stroke to increase the displacement, and the inside of the crankcase is relieved in order to clear the crank throws and rods. That's the main drawback to trying to convert a 95 HP... you have to do all the interior relieving yourself (assuming you're using an 8409 crank from a 110 HP in your conversion). Not a deal-breaker by any means, but it depends on your comfort level doing engine work.>and bore size.Right. Different cylinders.>I am also wondering if I need to get some sort of bell housingYes, the bell housing is what is used to make the front cover for the engine. The 'bell' part is cut off to leave simply the front cover. There are excellent photos of all of this on D.J. Vegh's and Pat Panzera's websites, so if you need more guidance don't feel like you're out there on your own.>I do plan on getting William's conversion manualDon't just plan on it... do it! The conversion manual will answer all your questions and more. But for now, don't pass up this 95 HP engine if it's complete and if it can be turned by putting a socket on it and turning it over (or if it was running when removed from the car).Oscar ZunigaSan Antonio, TXmailto: taildrags(at)hotmail.comwebsite at http://www.flysquirrel.net________________________________________________________________________________
