I have a .010 overbore on a 454 Chevy with an RV cam and Holley 2-bbl Pro-jection set up. The engine is installed in a 67 Chevy C-10 carrying a Open Road chassis mount Class-C motor home body.
This unit is heavy (apaprox. 14,000 GVW when fully loaded and operated primarily in Arizona with engine A/C on.
Question: Does it seem reasonable for this set up to require:
1. Ron Davis custom NASCAR radiator (1" tubes),
2. Flex-fan on engine
3. Four electric pusher fans in front of radiator and a/c condenser,
4. Two combined transmission oil/engine oil coolers and 1 engine oil only cooler stacked behind one another and connected in series with a blower fan in front of them,
5. Air vents cut into engine hood,
6. Ram air intake ducting above hood air into throttle body,
to run at 220F when the ambient air is 105F?
I'm wondering why this set up runs so hot? I have had to add all these apurtenances to get this thing from 250 down to 220 on a hot day and the engine is not burning lean. The only thing I haven't tried is "wetter water" in the coolant system.
Any ideas why this set up runs so hot? I'm thinking about switching to a crate 502, but after all this heart-burn would like to salvage this set up before spending more $$.
Thanks in advance to anyone who cares to respond...jsc
