I am needing some help with this problem. I am attempting to find and intstall an engine into my 1966 chevy truck, however I am no great mechanic, I do know my way around a motor but this is over my head in job undertakings. What would a good engine for my truck, Im thinking 350, 305, or 283? Which would be the least expensive, easiest to work on, and least modifications on the truck? I am not looking to reinvent the wheel just want to make my truck look and run better. If anyone could help I would love any input you could give. thanks again for your time.P.s. Any articles you direct me to follow on any previous issues would be great. I used to keep all my mags and had to toss them.
first thing...what do you have in there now????engine of your 1966 Chevrolet C10 1/2 ton P/U 2WD:Available engines6 Cylinders 3.8L 1BL this is a 230 six6 Cylinders 4.1L 1BL OHV this is a 250 six6 Cylinders 4.8L 1BL OHV this is a 292 truck six.8 Cylinders 4.6L 2BL OHV this is a 283 V88 Cylinders 5.3L 4BL OHV this is a 327 V8a LOT of people have installed 472/500 caddy motors in those... with ease.. along with the caddy TH400 transmission... the 472 and 500 motors are LIGHTER than a small block chevy also.. with adaptor plates that are available.. one can even run big block chevy headers... i would probably leave the stock caddy log manifolds.. i have not paid attention to how they installed the caddy motor...but they did it with minimum tools.. the only issue now a days is finding a good one... and making sure that you replace the timing chain before installing it.. and getting the crank hub off without breaking it to replace the timing chain.. depending on your end use... you could install anything thing from a 4.3 V6 chevy or the V8 versions... do you want to keep a carb... do you want electronic ignition.... do you want to attempt to swap in a throttle body fuel injected motor.. there are about a dozen truck magazines on this site... over the next few days.. i will look around for swap articles... you can use the search window above right.. or the technical link above left...
I have the original 235 inline 6 with the 3 speed transmission, I have some of it taken apart. My end project would consist of having the ability to tow some things... nothing too heavy though. That is a lot of great info. I do appreciate any and all info as to at least get the truck rolling so I can do some shade tree mechanic work on it.
66 should probably have a 292 chevy .. i think the 235 stove bolt motors went out a few years earlier..292The 292 was only used in Chevrolet and GMC trucks; the block deck is taller, along with a relocated passenger-side engine mount. These were produced between 1962 to 1990; production of the engine shifted to Mexico after 1980. Year 1988 (only) 115 hp @ 3400 rpm and 215 lb. ft. @ 1600 rpmL25The L25 was GM's "last" pushrod straight six engine, produced from 1977 to 1988. It was used in Chevrolet trucks, displaced 292 cubic inches (4.8 L) and produced 115 hp (86 kW) and 215 ft·lbf (292 N·m). This engine was commonly used in UPS trucks through the 1980s, before being replaced by the 4.3L 90-degree V6.unless i am mistaken..
you will want to check this site off..seems they have some info on the frame brackets to mount the motor to..along with some pictures...http://www.persh.org/Pickup/perches.htmhttp://www.persh.org/Pickup/IdeaPage.htm
while thinking about a V8... you will probably want to think about electronic ignition...you will want to convert the early style igniton to the later dash mounted ignition... so the ign1 circuit does not open during cranking...
all engines you named would be about the same trouble. all would be about the same to work on. if you are going to use stock engines, 350 would have most H/P.
I went to a 350/700r4 combo, and never looked back! There are some pictures of my trans crossmemeber on here, and I just had a welder friend weld me on some new motormounts, so I could put the motor right where I wanted it. Of course, then I had to shorten, and have the yolks switched over on the driveshaft by a machine shop.
