Technical Whats a 337 flathead worth nowadays?

Gotta ask ... an 50’s/60’s vintage 392 or the newer 392 Hemi? I assume since you talk about potentially rebuilding the 331 that you’re putting the older 392 in there, but a newer one would be pretty sweet as well.

 

New 392? Don't open the hood...they just don't appear as they used to.

 

I hear ya' Mike. I've had the hoods open on several new vehicles with hemi's and haven't seen an engine yet!

 

About the 337--The Queen Mary is still looking for an anchor.

 

Sorry to create a stir! It's a 1957 392 with 10.5:1 pistons. We are using the dual quad setup from the 331. Engine and carbs are freshly rebuilt.

 

Also didn't mean to hijack your post 42merc. Good luck on the search.

 

Whether you want to use the 337 depends on what you want to use it for. I personally like the 337 because it’s unique and not often seen around. It really is a beast of an engine compared to the Ford flatheads. Definite conversation starter - if that’s what you’re going for.

But if you’re looking for an engine that is relatively cheap to build/upgrade, and makes lots o’ power, the 337 is likely not the best choice. Probably why they aren’t all that expensive to buy. Also make sure whatever you want to put it in has a front suspension that can take all that weight.

 

As I indicated before, my '51 came with no engine but there were many 337 Lincoln parts in the trunk. I gave the intake to a clever friend of mine who turned it into a tri-power intake. Amazing, looks "original". I'll get a picture if there is interest. I'm locked into (happily) a '51 Olds 303 I found complete and cheap. Will have a McCulloch VS-57 supercharger and a Carter WCD 2 barrel in a Kaiser bonnet.

 

I'm interested in the picture of the 337 tripower intake.

 

Tons of cool info on here. Good news, the dude said $150 for the motor. He just wants it outta the way. Im gonna snag it this saturday

Just a thought MuntzManMike, M-133 is a very low number, could your car be an early '51? Glendale cars went to about M-126.

 

Here's pics of my friends "tri-power" 337 intake he fabricated.

 

How very cool.

 

Yep, he did a bang-up job on that intake. Is it iron or aluminum?

 

^^^^^^^^^^^ Looks factory !

 

It's based on a factory cast iron single 2-barrel intake.

 

If you didn't already, and he still has it, I'd say buy that 337, but try to get a better price. If it is ready to run, or even if it needs a hone and some rings plus a valve grind, it won't be too costly. But if the rod and main bearings are shot, and/or an overbore and pistons, the cost is going to go way up.
I yanked a337 out of a junk 48 Ford F7 to use in a future project. I have heard lots of rumors as to their weight, anywhere from 700 - 1200 pounds. Since my buddys scales where over at my place, I decided to weigh this thing and see for myself just how portly they actually are. I figured it was best to weigh it bare of any accessories, since lots of guys would be adding their own lighter versions of that stuff. The stock flywheel was 47#, the bellhousing was about 50, the 5 speed syncro trans weighed 240, I left all that off as well as the exhaust manifolds, oil filter, dist, carb, fan, generator and starter. It still has the crank pulley and water pumps on it.

700 pounds even.

With a set of aluminum heads and an aluminum intake, it dropped to #635.
