in a 289 engine rebuild, what items need to be replaced? The heads have been skinned and worked a few months ago, so im sure they are fine. Would roller rockers be a good investment and do they require a special cam or pushrods? Gaskets of course, what about the cam and crankshaft? The cam is not stock, so if its in good condition ill keep it. If the crankshaft is not beatup and worn because of bad bearings, should i replace it? Crankshaft bearings are easy to replace, but what about the camshaft bearings? I plan on getting new pistons so rings will be on, what about the connecting rods (if they are in good shape)? Pushrods? Oil pump? Fuel pump? If the cylinder walls have no lip, should i bore it? Intake and carb are fine. Thanks to all.

You should have the crank miked and probably ground if it needs it ... have a reputable machine shop advice you on the crank. Use the existing rods ... again have the machine shop check them out.

Yes, you can do rod/main bearings, but cam bearings need special equipment ... have the machine shop do them.

If you go with roller rockers, you must use hardened push rods, and will also have to have your heads reworked for screw in studs and guide plates. A cheap alternative is the roller tipped "rail type" rockers by Crane. At least that way you get rid of some of the friction at a fraction of the cost (that's a cool saying, huh?).

Always replace the oil pump. It doesn't make any sense to go to all that work, and not replace the oil pump which is cheap and a PIA to replace later. Same goes with the timing chain and gears.

Also replace all freeze plugs.

Fuel pump is no big deal ... just use the existing one. If it fails, it's 30 minute job to replace.

Good luck!

What is your budget?
What is the reason your rebuilding the motor?

Are you looking for a light rebuild just to stop leaks and increase oil pressure or you wanting to add horsepower? Figure that out first then see what makes sense from there.

If you do replace the cam bearings, it would be wise to have the cam bearing area aligned bored. You can actually get away with reusing them if they are in good shape. If you do want to reuse them, you can't get it hot tanked with a caustic solution that eats the cam bearing material. A place that cleans up aluminum blocks can clean yours up without wiping out your bearings.

Just a thought for info.
