572 Build

heyDartsport, I am starting a 600" build also. mine will be a street motor as well. it specs:

4.550 bore
4.625 stroke
572-13
13.5 cr
282/290 @.050 .800" w/1.7 jessel rocker arms
indy aluminum block
isky bushed lifters
oliver rods 7.100

I want to only run the spray bar oiling, I have it on my 580" motor and it does really well. it really prolongs the valve spring life on the street.

question, my builder wants to modify the block for oil to the lifters. is it really needed? he says otherwise there is no oiling to the lifters. would splash oil be enough?

mine is going into a 68 cuda with a 4 speed........
