Hi all,
I Need a little help, this Inline thing is new to me but fun. I'm looking at buying a truck that is real straight (sans the customary rot on the rockers and bottom doors.) But the engine seems to have given up. The current owner re-tells a story of a loud back-fire upon engine start then a bad knock, not sure if from the valve train assy or the crank. He isn't much of a motorhead so it has sat like that for several years. My intention is to diagnose the failure and make the right offer. To this end he will allow me to do some wrenching before I buy. I have done some preliminary investigation on what he has, here are my findings:
Here is the specifics:
1960 C10
Block 3769716 (1960 number)
Head 3701887 (1953 number)
Questions:
1.) Is there significant difference in head performance/design, it bolted up all right but is this mismatch problematic?
2.) Do I have a "High Oil Pressure engine"? I think so but would like some conformation.
3.) I intend to stay with the inline but seem to find the cost of parts higher and the availability of cores short on the 235. If the Rotating assy is shot is it more economical to go with a newer 250 or 292. Is this a good observation or am I not looking hard enough?
4.) The Clutch was replaced some time back and he needed to use a 1967 6 cyl camaro clutch assy and the Bell housing didn't mate exactly right ( the mouning holes seemed to be elongated, without sufficiant tourqe it moves around its center axis This sounds Like a problem to me, any thoughts? Even if it fit the gear ratios must be off.
