I have a 65 C20 with a 283 already in it. It's a nice clean truck. Getting ready to sell it. Maybe a trade with cash? If interested. Is yours currently a driver? This one is, just put on a HEI distributor. It has a 1 ton Eaton rear end. Solid floor boards an minimal normal rust spots to be repaired, primed and painted? It's maroon in color. Let me know and we can exchange pics/specific info. I was hoping to fetch 10-12k for mine with a little more work; then it's off to Hot August Nights in Reno, I live 2 hours west in Gold Country Foothills. BTY, this is a long bed "step side". Trying to find out exactly how many C20 step sides they made that year...I think the number is very low, very rare truck. What do you think? John

If you have a 1956 v8 chev engine ,its likely to be a 265 cu,in.You have a 3/4 ton truck so leave the 292 in it even if you have to rebuild it as it has more torque than an early v8.Your creating all kinds of unessary work by using the v8 that old.For example check to see if the lower rad hose comes out on the correct side,then your motor mounts are incorrect, then your clutch pivot between frame and motor is incorrect.If your determined to v8 your truck you should start with an engine that has 3 motor mount holes on the block under your exhaust and also very important a3/8 taped hole right above theoil filter to look after your clutch pivot.Look for a truck thats been done very closely,Good Luck Don
