I second the motion on the pricey Derale units. Those and a big BeCool radiator worked on my no airflow Trans Am front end.

The twin 255's will be fine. I'm getting ready to see how far they can actually be pushed (another month or two and my Vette will be running, and I'm aiming at 1K RWHP on stock lines/twin 255's).

P.S. I was running a 383 also.

ohh my bad, for some reason i thought you had all this on a 355. i may take a chance on the stock rad since mine it still in pretty good condition and never had an issue keeping the 383 below 180f

I was close

I would run triple 255s fastbird or, double 450s

Sorry for thread hijack OP

no worries, all good info

so looks like i will give the twin 255's a shot, will be cheaper for me since i already have a 255 in the car so it will just be getting another one and some fuel line which i may already have and a Y. good thing i already have the dreaded trap door mod done so it should be super easy to pull the sending unit. another thing i was thinking, should i be upgrading to an aftermarket FPR or can the stock FPR handle the added pressure?
