[QUOTE=Adams' Apple]I don't know that info, either, and I'm not sure if it's published anywhere. I can look in the Service manul...it may have amp specs, but not sure about CFM.
Welcome to C3VR, btw!!
Be sure to check out our sister site, specifically for C4 Corvettes at
C4vetteregistry.com [/QUOTE] yeah finding out the fan cfm is a tough question,i dont think its recorded anywhere except at the engineering department at general motors,and to contact them is impossible..maybe one of the after market fan companys is willing to do a test on one...im not too worried about the amp rating,i could alway turn the fan on and use an amp gauge to see how many amps its using..the cfm is what i realy need to find out...vettes are supose to be high performance,so i imagine the fan is supose to be too...thats why its important to know the cfm...example:if i was to buy an aftermarket high performance fan,it might blow out the same cfm as my stock fan...im going to check out that other site...hopefully someone will know...after this fan issue is resolved,my next project is rebuilding my 383 stroker motor to drop back in my vette...i put a 307 chevy motor in my vette 2 weeks ago to hold me off until i rebuild my 383 stroker...i wore out the cam,oil in the plugs and smoking like crazy...i ran that 383 since 1998 in my camaro and my vette...believe it or not that 307 motor i put in my vette burns rubber...its got some pep with the carter 750 carb..
