taking out radiator - cooling options
wideopen231:
As have said here and few other sites ,I have rub dry blocks with alky since 1986,not that I have raced non stop since then. I have run it as normal system and used some tuning tricks to cool motor on return road.Never had issue. Now running round robbin could be issue if not cooling engine by running touch rich at time. Yes you might have to change oi more often than some like but for me that not a big deal.
With my deal.Solid block and billet hads its not even a option so know few tuning tricks will be a must.

Its the side by side exhaust valves in a SBC that creates the problem that the cooling or temp stablazation is a benifit. Chrys with their top and bottom valve araingment in not affected and can run as billet.

Exactly I never started having problems eating head gaskets until I started to lean on it, 7.20's head gaskets running dry would last me 3-4 events once I started running 7.0-7teens the gaskets would go away pretty quick. Now running water in the heads I can get away with 6.60's-6.70's for a season on the same gaskets which for me is 40 or so passes.
