I've found a radiator, looks like part number 2785970. Seller says it's out of a 67 Barracuda and a 3 row. Roseville guide says for a 273, do you think this would cool a 400ish horsepower 340 (living in the Northwest). Thanks.
As long as its clean and in good condition it will be fine.
You'll need a shroud too.
I have the same radiator but a lower performing engine and my car runs at 180 all summer long.
I just had a radiator re-cored for a 70 cuda' 340, it ran me $380.
Let us know what it runs you.
I hope your changing the water pump to 69 and earlier style otherwise you wont be able to use that early a body radiator.
Wow, that's really expensive! The guy I use has been doing radiators for about 60 years, and he is in the $300 range all day long! Yes, it's driven by the price of the core, and I'll bet those custom cores can be really expensive! Never had the need for that much cooling myself, so I stick to the classic 3 row!
Glen-ray probably has, or the parts to rebuild one for you. Would have cost more but come with a new core etc. Also don't judge their prices based on the rare number - dated ones. Some radiators are less, repairs are less, etc. I figured you've already commited to the local guy so didn't see any reason to mention it.Yeah, probably a 2898031 or something built for a 340 auto would have been the best. Looked quite awhile for one, hard to find with inlet/outlet on drivers side. I found plenty that had already sold from $300-$450.
Why not just get a factory style replacement like from classic industries? I have one on my demon and my car stayed at 180 and maybe crept up to 190 in stop and go in 95 degrees. Just recently replaced the 5 year old murray water pump due to some slight play in the bearing, with much advice from the members on here i upgraded to the milodon high flow water pump paired with a milodon high flow 180 t stat and it seems much more efficient. Actually can see when the t stat opens, opens at 180 and drops to 170
