HumberSS Posted October 28, 2024 Posted October 28, 2024 Cool cars. Got any pics of the 61? My mate had a 61 plymouth coupe years ago in welly he daily'd (dereg too!) back when gas prices were 2 digits.. it was Matty B and dropped on its ass with a small block. I loved how weird/cool/ugly it was. Mopars of that era are just so awesome. 1 Quote

dmulally Posted October 29, 2024 Posted October 29, 2024 I've had a couple of dodge flatheads over the years. Really solid engine and there are still bits for sale that aren't too hard to find. I recall getting a lot of parts out of Turkey when I rebuilt my last one about 15-20 years ago now. Dusting off my memory bank if you want a quick way to ID your engine just measure the length of the head. If it's 23 inches it'll likely be a 218 or 230. If it's 25" then it could be a 228, 237 or a 250 iirc. Most common I found were 230 and 250. 1 1 Quote

Will try and get some next time I'm around there but definitely needs more work than the Dodge Quote

Yeah it's a 25 inch block - so I'm thinking 230/250 as well, guess we won't know for sure until we get into the engine and figure our bore size. 1 Quote

Designers told to go as distinctive as they like but maybe went a bit far for the market at the time. Anyway - I'll put a forum up about the Plymouth too in due course! Got the garage open just need to clear a wee bit more room to get some decent photos. Might be a weekend job. 2 Quote
cletus Posted November 10, 2024 Posted November 10, 2024 Rockauto will be your friend for engine parts I *think* the US model equivalent would be plymouth savoy, same year had a 230 in it There's probably enough info on the rock auto listing to figure out if it's the right part Good to see you making progress! 2 1 Quote

Thanks very much - think the plan from here is to get the block to a reconditioner to get a better idea of what we're looking at and make a list for parts to get the thing runnings. I think everything for the gearbox is around home - fingers crossed! Quote
michael14 Posted November 10, 2024 Author Posted November 10, 2024 Also - does anyone know what colour the flat head 6 would've been? All I can find online is aluminum silver - but the photo on the project thread looks like it could have been blue (probably clearest below the oil filter) in the photo I posted) and maybe even gold on the top?

Truenotch Posted November 11, 2024 Posted November 11, 2024 It looks like they came in a bunch of different colours. Google image search "Chrysler flathead engine" and you'll see more. 1 Quote
shrike Posted November 11, 2024 Posted November 11, 2024 If yours is the 230 sized motor Looks like the biggest oversized pistons rockauto have are 0.080" oversize They do have sleeve repair kits too They also have standard sized valve seats. Looks like they are running short on new valves. Not much oversized stuff left Summit racing has some options but alot of it is special order Summit racing link (searched based on the 230 engine size 3.8 etc) Summit racing link 2 (specific search based on Clints comment that its the same engine in the Savoy) Are you sure you want 3 7/16" pistons? As that's over 87mm Factory bore 230 3+1⁄4 in (82.6 mm) The bigger displacement engines has that size tho so possible it's been bored out already? Or is a 237? Apparently the Canadian and American based flathead 6s are different. 3+7⁄16 in (87.3 mm) Larger pistons https://en.m.wikipedia.org/wiki/Chrysler_flathead_engine Looking at the pics/info and I'd double check when you order but looks like new pistons are all the newer 3 ring design so may even be an upgrade 1 Quote
shrike Posted November 11, 2024 Posted November 11, 2024 Going down the rabbit hole of pistons and modifying for some more power "There are some modern Harley and Indian flat-top pistons that might prove useful for someone building a modified flathead. All the pins are too small, but a new pin bushing fixes that. Bore sizes: Chief 3.25" H-D UL 3.3125" H-D UH 3.422" H-D XL Evo 1200, FL 1340 (same bore, different compression distances) 3.498" Corvair 140 3.375" Corvair 145, 164 (same bore, different compression distances) 3.4375" " Reference link if you can find a long rod option you could run shorter modern pistons (assuming you found something that fit) Guy has already made custom gear but its expensive Expensive custom long rods/short pistons Quote
440bbm Posted November 11, 2024 Posted November 11, 2024 I think you need to clarify a bunch of data. All the machine shop should be able to provide. What is the block cu in. what is it likely to require to clean up? then can figure out the piston availabilty range. there is a metric buttload of piston manufacturers out there and from the small amount of looking it appears there is some about but no point getting too serious without knowing what it is going to require at a minimum. They can measure the grrove depths and use that plus bore size and advise what it will likely need at a minimum.if they cant provide you this ort of info then take your engine elsewhere as they aren't that clever. This is a very simple motor but quite different to the new stuff which does need to be treated and handled like it too. So you want to find someone that is capable / expreienced with these old girls. check this, if it is the 3 7/16" bore. UEM Pistons 2 Quote

As that's over 87mm Hey there - Tony who is helping me out with the engine measured the cylinder last night when I was around there to 3 7/16"- maybe it has been re bored previously, but that I'm unsure of. 5 hours ago, shrike said: Or is a 237? Apparently the Canadian and American based flathead 6s are different. I hadn't heard of any of them being a 237 - perhaps? Those 37P pistons appear to be 3 1/4" bore, so not sure they're the ones. Even at 0.08 oversized then it would take them to 3.33" roughly 3 5.28/16" - so still smaller than 3 7/16" 5 hours ago, shrike said: Apparently the Canadian and American based flathead 6s are different. Like you, everything I have found appears to be that 3 1/4" bore but I potentially think that may be a difference between the American domestic (23.5 inch block) vs Canadian (25.5 inch block) - I'm certainly no expert so nobody quote me on that!
