Hate to be a pest. But I've got another concern.
A friend that builds chevy engines just told me that when I installed the Melling High Volume oil pump, I should have enlarged the oil return holes in the heads. He claims it's a must for chevys and I'll end up pulling all the oil from the pan on cold mornings.
Has anyone used this oil pump and have you had problems as my friend mentioned.
I run a Melling HV57 on my 70/390 and as long as your not spnning the hell out of the motor for long periods of time? you'll be just fine !
the block that in my truck now has No oil mads done to it..C$ heads without any restrictors..and has been just fine !! The next Engine will be another Story tho it will see 6100-6200rpm.. and will have the mods done..

If you're worried, put the oil restrictors in the heads.

I just put #66's in my ol 352. That's ~.066 and it seems to be fine for the last week or so. Seeing that I don't turn it over 3000 rpm...I think I'll be fine.
Maybe if I it was a hot rod and liked to turn some rpm, I could put something a bit bigger, but they were handy.
I did notice that the oil consuption is down drastically from before this. I think it helped the lack of valve stem seals.
