SoCal with 390

Hey Guys,
Any socal (LA area) that runs a 390? I just purchased a fastback with a 390 in it and would like to get a sense of what the "normal" operating conditions (i.e. heat,noise, throttle response & gas mileage). Would be great to check out someone else's setup in person.

Thanks!

My 67 FB started out as a 390, but with the 428 CJ crank,428 CJ heads, and forged 30 over 410 pistons, it's now a 416. It runs warm to hot depending on the timing and outside temp. A cooling system in top shape is a must. I went with a moderate cam (Compcams XE262) so that helps. My best mileage to date has been 13 MPH on a 3hr road trip from Lake Isabella back to Ontario. Plug changes are a pain, parts are expensive and tougher to find compared to a small block. But the looks on peoples faces when you pop the hood makes it all worth it.

How are you guys cooling ? I *think* I solved my stalling problem... it is not overheating but I haven't pushed in 1 hour 405 traffic yet. What kind of radiator are you guys running?
I'm thinking of replacing the stock radiator to handle future upgrades like A/C and power steering.

Thanks!
