hello


I am thinking in doing a reverse cooling conversion for an aftermarket SBC head ( Dart Pro 1 ) to use it on LT1 block

there is no much difference in water ports between the SBC and LT1

I just have to weld shut the water ports that go to the intake manifold and drill and tap ports for crossover tube ( and modify the heads or LT1 intake for intake bolts pattern )

but I wonder if there is any difference in oil draining ports between them
any one have pics or drawings of the oil drain port in SBC heads ?

look at the attached pic



any input appreciated

thanks

Please explain what the notation in your picture means.

The bottom picture is the FelPro revised cooling passage. It is an early SBC mod. It has nothing to do with LT1s.

please ignour the a b c d on sbc gasket pic ( I took that pic from Chevy Hi Performance site )

the red dots are for bolt locations

my point is :
the openings in the two gaskets are the same except for the big water passage in the top of LT1 gasket and the oil drain openings in LT1 head

the LT1/LT4 heads drain directly to the lifter valley

so how ( where ) do SBC heads drain oil ?

check the now attachment

thanks

Oil drains are at each end of head.

do they drain into the valley ?

thank you very much

[malc]

This is where the oil drains back, into the valley.

thanks a ton

now I guess modifing the oil drain is not required to fit on a LT1 block
