Hi Ed,> If you can provide any other suggestions regarding how to select>the correct Corvair engine for conversion, i.e. which cars and years are>best, that would be great. For example, I know a guy who has a Corvair>coupe, a station wagon, and a truck-like vehicle (I don't know the names>of these models). Do you have any suggestions as to which one would be>best to go after? I know that the coupe has a standard transmission.For aircraft use, a 110 hp engine from between 1965 and 1969 is generally preferred. Although the 1964 engine had the same displacement and hp, the outside diameter of the cylinder jugs was a bit smaller, so replacement parts are a bit harder to locate. There are other minor differences.You will find an identification number stamped on each engine on the day it wasassembled. This number contains the date and a code for the plant in which itwas assembled and a code for the engine configuration. For example, T1215RH means that it was built at the Tonowanda plant on Dec. 15 and it is a 110hp ona powerglide tranny. Half of the Corvairs built between 1965 and 1967 have this engine suffix code, and it is ideal for our application. Other suffix codes refer to combinations of accessories such as air conditioning, emmissioncontrols, manual transmission, etc.The number is stamped on the top surface of the crankcase near the place wherethe two halves are joined. It can be seen, under a thick coat of black goo, without removing any parts. It's on the same surface that the air blower is attached. If you find the code, you can post it to the Corvair Center Forum:
http://www.loop.com/~yujisilva/ , and the friendly folks there will tell you everything you want to know about the engine. Here are suffix codes for 95-110hp engines from 1965 to 1969:RA,RD,RE,RF,RG,RH,RJ,RK,RR,RS,RU,RV,RW,RX,QO,QP,QS,AC,AD,AEIf you can, I would advise sticking to an engine from a powerglide car, as thishas less potential for abuse. The truck (Greenbrier or Rampside) is more likely to have a 95 or 80 hp engine, since the torque curve is more suited to truck applications. Don't know what to expect in the wagon (Lakewood). Both ofthese are most likely early model vehicles (pre-'65).--Peter________________________________________________________________________________
