disassebled sbc help

i got my uncle a great running 350cid 260 hp marine engine to build for a 69 nova he was going to build. he got the rolling car built and then disassembled the engine with intentions on 400 hp. at that point he lost his health and lost a battle with cancer a year and a half later. at that poin the engine was offered back to me by his sons(my cousins) who put a machinist build 454 in the car and painted the car the way their father had dreamed of. the bad part is the engine was going to the machine shop so the marine steel crank was oiled in a bag, and the lifters trashed, and the rods still attached to the pistons dipped in used deisel oil, and camshaft shelved, nothing marked. i would LIKE to reassemble this engine cheaply for a buddy of mine for christmas, that is down on funds and runs a tired old 88 C 1500 that he dreams of restoreing. i want to know how i would find out where these rods and pistons went. i do not want to spend 1800 bucks line honing and boring block, recamming and reconditioning rods and new pistons whene this engine would have had another 200,000 miles hiding under its carb. i wouldnt put this engine back together withought plastigaugeing it with new bearings and new piston rings but that is 300 bucks worth spending. how much life could i expect from the cam if i put 16 new lifters on it? also in speculation, how relieble could this engine be if the rods were to not make it back to their origional cylinder? what is the bottom line here?

Actually what's important about rods is that the cap and shank match. The cylinder they came from is not important as long as the piston and the rod have the correct orientation. All the pistons have a notch or arrow on top this needs to point to the front of the block in all cases. The rods have a chamfer on the bearing end one side is larger than the other, the larger chamfer always faces the cheek side of the rod throw, so on any throw there will be a forward facing large chamfer with a piston notch both faceing forward, there will also be a rod with the large chamfer facing to the rear of the engine with the attached piston's notch facing to the front of the engine.

If they seperated the rod caps from the rod shanks such that you don't know what goes with what you're more than less got a job to do. Now you've got to figure the match of cap for each shank. This will be visual and slow going you're looking for when the bearing indents are aligned on the same side that the cap and shank bearing diameter meets smoothly and the outside thrust surfaces from and rear of the rod also meet smoothly and the bolt holes and bolts align. Not impossible to do just a PIA to do.

well then that is good news becasue the rod caps and nuts apear to have been reassebled on disassembly, in the right order. that is quite a load off. how about lifters? would new lifters on the old cam be in order or would i need to start with a fresh cam set? otherwise this is just a freshen up job and the engine will go to a good home. sooner than later.

New lifters on a used cam is inviting disaster these days. Or even changing cam/lifters to a different block. I have a customer that installed a slightly used cam and lifters (less than 1000 miles). From his old engine. Into a new engine for his street only ElCamino.

Lifters were marked to the lobe and assembled with break in lube and zinc supplement in the oil. Valve springs set at 95 lb. on the seat. Roller rockers.

The engine wiped all but one lobe off the cam in two weeks time. .

Check the sides of the rods and caps, look for numbers on each rod and cap. This tells what cylinder the piston was in. Replace the camshaft with a cam and lifter kit from Summit Racing. These are great cams for the price. Summit Racing Street & Strip® Cam Kits SUM-K00052 - SummitRacing.com

Hows your cam look, If its not pitted and metal isn't rolling on the lobes and the old lifters look good on the bottoms not bowled or pitted you can run new lifters on it, but you must brake them in just like a new cam break in! Dealers and racers and hotrodders have done that for many many years! If it was the case that you cant run new lifters on an old cam, dealers would change cam and lifters every time a lifter was replaced because it wouldn't pump up and made noise! If the cam lobes are wore they will probably wear out the cam and lifters pretty quick!!!!


You Don't need to take the chance. flat tappet cam kits are cheep!

honestly i would prefer to use the old camshaft. it looked great so i took it to a machine shop to be checked by knowing eyes and he said it could be reused with new lifters following a proper break it procedure. his services were 25 dollars and the information i gained from the machinist was the same information i was given on this here forum. sais somethin boys...how many people have you helped save a bundle of cash? knowledge is power thank you guys so much for adequate information ill be sure to spread my knowledge here and thank you again for your superior helpfullness. this will be a great christmas present to my buddy who just bought a house and has little or no money. its payback because he gave me a woodstove and all the pipe for my new house 4 years ago!
