the spare I have is a late model 235 from a car. It has hydraulic lifters. Is the cam from the truck engines, with solid lifters, ground to give more torque? I do want the torque and obviously have no interest in a racing engine. should I replace the hydraulic lifters and cam from the car engine with solid lifters and a solid lifter cam?
besides all that, the rest should be good to go, right? the cylinder walls are nice so I won't go oversize (budget doesn't allow for machining anyway). It's got the 848 head so that's good.
any other advice to consider when reworking a passenger car engine to a truck engine? thanks! | | | | | Joined: Jun 2004 Posts: 8,597 Riding in the Passing Lane | | Riding in the Passing Lane Joined: Jun 2004 Posts: 8,597 | There is not that much difference in the cam specks. If the lifters & cam are good I would use them. Hone the cyl. walls & clean them good with soap & water. Replace the rings & inserts & send the head out for a rebuild. That will perk it up.
They say money can't buy happiness. It can buy old Chevy trucks though.

There are cams available to enhance, and raising compression would certainly help...BUT...your 4-speed will easily allow driving with a stock motor, just not much heavy hauling at speed (or drag racing ;))

If you can't fix it with a hammer and screwdriver, you need a bigger hammer.1965 Chevy C10 | | | | | Joined: Feb 2000 Posts: 5,229 'Bolter | | 'Bolter Joined: Feb 2000 Posts: 5,229 | For sure get the valves done, if you have the money, true up the head surface, it flattens out the head in case its warped and will raise the compression a bit.

cm I do a lot of heavy hauling. so much that the axle hits the rubber blocks on the frame. always goes 65 mph down the interstate. and that's with the stock 235. anyway, I might keep the hydros. I'm afraid I'll miss the sewing machine sound though. Rings bearings etc was already planned, just as a head job, did one to the engine that's currently in the truck and that turned out to be some well-spent time. If this head is still straight (whcih I still have to check) the work on the head is super cheap as well, lots of gain for little $$ | | |
