Hi again,

To review, we have this 1/2 ton Chevie pick-up that's in a lot of pieces courtesy of the previous owner. It came with what he said was a 54 chevie in-line six that turns out to be stuck tight. It's so tight that even after getting the pistons free by taking the rod bearing caps off and driving them back the engine still won't turn. We now wonder if the camshaft is froze or what. The main bearing conditions tell us the crank needs turning, etc.

So it seems wise to consider another engine altogether and there lay the basis of my earlier questions. yesterday I visited with an old-timer north of here who has in his woods collection several Jimmies between 50 and 70. One is a 3/4 ton that reportedly hadn't been started for over a year and it started right up (same battery, even) and sounded good and didn't seem to smoke. However, it has the side mount rather than the front mount that the 218s and 235s have so that's a problem---or, is it? Is it possible that the mount bracket from my stuck 235 would bolt on the front of this engine? Incidently, this engine says "302 GM 1970" or facsimile on the engine near the distributor. Maybe that's too much engine for my purposes to start with?

Another available from the same source is a 50 1/2 ton jimmie whose engine turns over but hasn't started yet with a battery transplant and filing the points. Probably needs a coil--the old guy said he drove it as recently as two years ago. It appears it would fit without much of any modification. Both these jimmies have four speed trannies. His asking is $200 for the whole 68 truck and $100 for the whole 50. Those prices don't sound bad if in fact they don't need o.h. What'd think?

A body shop guy recently told me that the older, smaller chevie v8's would also fit to the 46 bell housing, clutch and trannie. Is that likely and, if I'm going to be building mounts might this not be a viable option? I think I can find a good condition v8 fairly easily.

While looking thru this old-timers woods and his 100+ collection of stuff in various stages of decay I found several vintage chevie cars including a 47 four door sedan, a 48 coupe (he calls it a coupe--it has the slant back with only a smallish rear seat space), and others. These bodies aren't very full of cancer--no idea of motor condition. Are these things worth hauling home?

This has rambled on--will appreciate any thoughts.
