Do the regal 307 radiator have the oil and trans line holes?

I just ordered one from RockAuto, their distribution center is not far from my work but they don't sell directly. I'll be replacing the stock radiator which is probably clogged, temps got up to 210 w A/C on in stop & go traffic during in mid-July when it was high 90s here. This weekend with low 90s and A/C temps stayed around 180, but once I got into boost a few times it got up to 195. I'll post my results this weekend.

Did you move the fan shroud toward the radiator?
Did you bypass the fan motor resistor?

I don't, still very new to the game. My gauges are on order from Kirban Performance - they're telling me 7-10 business days.

Tell me about scan tools! What do you use?

Scanmaster and Powerlogger from Full Throttle Speed and Style.

No just like the Fbody doesnt have the engine oil coolers just the trans.

I haven't installed it yet. I plan to just swap the radiator and used RMI-25 and distilled water instead of 50/50 and see what the improvements are before making any other changes.

Got the new radiator in. Same as the stock size but with plastic end tanks. Running in the garage for 15 minutes the temp stayed around 168 where the stock would be 190+. I took it out and got into boost many times and max temp I saw was 175 and would steady at 170 when cruising.

It's made for turbo buicks. I got from rockauto. It has the same oil cooler and trans cooler location.

Don't worry about tracking down the previous owner. They all do this. It's the nature of the beast with 3 decades and horizontal flues.

Earl, that is a stock replacement for a tb. It has both engine oil coller and transmission cooler. If you scroll down to the very bottom of the link you'll see the specs. It's the f body radiator with the correct side tank. They've been making them for a little while now.

Oh yeah, the one with the neck down bushings that cause the transmission lines to interfere with metal. I had one of those a while back that I sent back.

What t-stat are you using? I went with the stock 195...hopefully I won't regret that!

I'm not sure since I didn't change it, probably a 180.

You will. I'd swap it out with a 180 and drill a small steam hole at 12:00.


...or take your 195 and drill a BIG steam hole at 12:00

Went for a ride around 2 PM, outside temp about 93. A/C on full blast, hottest it ever got was 181 sitting at a light for a while. Cruising temp is low 170s and got up to 175 going WOT on the freeway on ramp.
