Things to tell engine builder

[silverblaz]

I was wondering if there are things that i should be telling the engine builder that people have run accross before.

like notching the block for the eagles i know that

Are there any tips or tricks for better oiling.

I have searched but thought i would see if there are some little or big things that people know of that could help.

who are you having do the machine work on your motor? i don't believe the block needs to be notched for the eagles, it's the clearance on the oil pan that you have to worry about. a high school friend runs vintage driveline who has a lot of experience with GM stuff. might want to see if he has any tips or can help. ask for jay. tell him warren sent you.

One thing I see come up time and time again is the Oil Dipstick Tube.
When you 4-Bolt your main caps the dipstick sometimes hits on one of the main caps.
I would suggest buying a new $7. dipstick tube and giving that and your dipstick to them to fit in with the build of your shortblock if that is what you are having done.
This is something that can be a real pain if you forget it and very hard to work on once the block is in the truck again.
Eagles only need clearancing on some blocks. Have them check anyway if it is very close clearance them. Also install the oil pan and gasket and check clearance of the pan this sometimes is an issue with some gaskets it seems. If there is any clearance issues just simply dimple the pan so they clear.
As far as oiling improvements I would only suggest you research an oil pump that wont crack off at the housing like some of the later replacement pumps.

Speaking of oil pan gasket, do we use the same gasket as the regular 4.3? Does our oil pan have the same mating surface?

We were just having this conversation this weekend. A local with a recent rebuild had to notch quite heavily.
My motor required no notches at all.

I haven't seen a pan that didn't need to be dented/pressed, though.

Dunno if it's block tolerance, or a particular casting lot, but it doesn't seem to be every block. It's definitely something to keep a sharp eye out for.

Double roller camshaft sprocket will proly hit oil galley castings on block. Also "stake" galley plugs. Be sure to degree the cam. Check rocker to valve geometry. :2cents:
