electric vs mech

my 350 with an auto no air had a 6 blade mech fan with clutch. It made so much noise in first I couldn't stand it. I switched over to an electric no I get a DIM light. no gage. I guess the big, noisy ,mechanical fan was the real deal.

Bore out your water pump. You wouldn't believe how restricted they are inside.

What do you mean "bore out your water pump"?

I think he's referring to cleaning up bad castings, sort of like what you do with water ports on cylinder heads.

SP383 GM Crate motor in my '70 Nova & I'm SO glad I went with a clutch fan! A Be Cool aluminum radiator (the one that mounts in the bottom cradle), factory small block fan shroud & a Hayden clutch fan. In bumper to bumper traffic it won't go over 182 degrees on a warm day...
