What do I need to do to rebuild a slant I have laying around myself? It’s off a ‘66 Clark Cortez and I want to do factory specs. Last I checked it had good compression in each cylinder but it’s been in an accident after that.
 
Before getting into the rebuild, I have a question. Are you going to keep the engine mated to a 67 or earlier transmission? Will make a difference. Also do you mean parts or tools or both?

We had a convertor made to mate large register crank to early trans...or basically new case with old 19 spline internals. Iir
Not sure if new would fit in old case, dont think theres room in the snout.

For that, a new converter is not required, just use an adapter ring it the end of the crank (I sell those). To go the other way (67 older engine to 68 newer trans) requires a custom converter, or putting the early front parts in the late trans.

I made a ring, out of pipe. Crude but it worked. On the convertor...that's what we did alright.
 
I assume that's a forklift. As such, you will need a passenger car distributor, as industrial style slants had a distributor with no vacuum advance. Other than that, I believe it is a standard rebuild. Find a date code on the engine and buy an appropriate dated service manual for same year vehicle with a slant.

Clark cortez is a motorhome isnt it?
 
Clark Cortez is a 1960s motor home, special chain drive transmission,also has the special downward side draft carb mounting intake.

Cortez rode like a car, had independent suspension all around IIRC. Ran into a guy with one at a Malibu state camp ground , had the radiator out and was waiting on a water pump to be delivered. You know, hoe fast do you want your motorhome to be? They were not all that big and they put slants in tow trucks and missile carriages.
 
If it has good compression, why would you need a rebuild? Confirm first. If the goal is just replacing seals and gaskets, that can be done w/ engine in-car and I have seen the gasket set for ~$30 on ebay. The rear seal in a slant is a split 2-piece ring. It is in a separate aluminum holder. You push the upper half around. You can also change all the rod and main bearings while the oil pan is off. I recall front & rear seals are same PN as for the 426 Hemi engine. When you remove the front timing cover, expect the chain and sprockets to need replacing (~$30 set). Of course, a good time to consider a cam and lifters swap. You can get better quality silicone gaskets from "Real Gaskets" (TN). Still assuming good compression, the only reason to remove the head is if the valve guides are worn, but oil sucked into the intake at idle is usually fixed by replacing the rubber umbrella seal over each valve. Read how to avoid dropping a valve into the cylinder. Also, replace the rubber seals on the spark plug tubes. rockauto should have everything you need.
