Cpt.Fred Posted March 24, 2009 Report Share Posted March 24, 2009 a friend of mine is coming over to the US from Berlin and we plan to get a large box for shipping, so along with other parts i REALLY need, i was thinking of buying a larger engine for a much faster future with the P-10... now i already know that the chrysler/desoto blocks are about 25" and the dodge/plymouth blocks are only 23" or so, but what would be the largest l-head fitting into my car without changing anything on the body? if i am not mistaken, i have a 201cui with 84hp in there right now. i don't want to change the original motor because its a matching number car with 78000miles, but then again i'd like to have a deuce intake and split headers and a finned aluminium head and... you know what i mean:) maybe you have photos, too?

Andydodge Posted March 24, 2009 Report Share Posted March 24, 2009 Fred, the 25" block will fit into the plymouth as far as I can work out by moving the radiator forward, the mounts are the same, just further forward.......but you mention the hop up bits you want......I have a 23" 201 cube engine in my 1941 P11 and have a 23' 230 cube engine I'm going to bolt in its place.....I have an Edgy Finned head, Offy twin carb intake and Tom Langdon makes the cast iron "Fenton" headers........all for the 23" engine.......I would have stuck a 25" 250 cube engine in it but as its RHD the longer engine hits the steering box on the oil pump, if your car is still left hand drive you won't have that problem and the Fenton headers will clear the steering also.......hop up parts are easier to find i think for the 23" engine also......andyd Quote Link to comment Share on other sites More sharing options...
Cpt.Fred Posted March 24, 2009 Author Report Share Posted March 24, 2009 yes, that's what i heard. offy and fenton didn't produce any deuce intakes and headers for those 25ers, so i've been told. sad though, because there is a 230 chrysler engine with everything still on it and turning for a small buck just around the corner here... guess i'll stay with the ply blocks first, i don't want to chnange too much on the car.

BobT-47P15 Posted March 24, 2009 Report Share Posted March 24, 2009 Has anyone ever considered sending their ol flathead to a "racing engine" shop?? We have one or two places here that build racing engines....but I don't know just which kind of race cars they go in. Stock cars, or drag cars or what......? I've considered stopping in one of them to discuss what they could do for my engine. Don't know what parts they have access to.....and wonder if they could build either a split manifold or headers.....intake, or what. Probably could balance it. Might be interesting to see what they say. Just a thought. Quote Link to comment Share on other sites More sharing options...
1940plymouth Posted March 24, 2009 Report Share Posted March 24, 2009 Cpt. Fred. Would it be possible for you to post some photos of your P-10 Thanks, Bob Quote Link to comment Share on other sites More sharing options...
greg g Posted March 24, 2009 Report Share Posted March 24, 2009 Supose you could cram a 308 hudson twin power in there..... Quote Link to comment Share on other sites More sharing options...
Cpt.Fred Posted March 25, 2009 Author Report Share Posted March 25, 2009 sure, here are some pics: Quote Link to comment Share on other sites More sharing options...
Cpt.Fred Posted March 25, 2009 Author Report Share Posted March 25, 2009 the inside looks completely wrecked on the photos, but is actually quite good. there are water stains everywhere, but the seat upholstery was covered all the years and is in a great condition. carpet is good as well. i'll try to rescue as much as possible, i want to keep the car like it is. except the hp... and i will lower it a little. it looks like we say here "a stork in the salad".

1940plymouth Posted March 25, 2009 Report Share Posted March 25, 2009 Thanks for posting the photos, she is in darn good condition compared to my '40 when we got it over twenty years ago. Bob Quote Link to comment Share on other sites More sharing options...
grey beard Posted March 25, 2009 Report Share Posted March 25, 2009 I have seen tractor pullers take Case engines from the thirties - model C's - that were only four cylinders weith long stokes but which had overhead valves - and build them to turn more than 4,000 rpms. These engines had babbited rods and mains. Can you imagine that? This was achieved by careful balancing and blueprinting by he builders. Of course they tricked up cams and intakes, etc.,but this goes to show what is possigle with any engine if you really want to push the envelope. I'll bet that just a good balance job on the lower end and a high cfm carb along with a competetive cam and stronger sprins could make one of our flatties turn 4,000 too. I magine that torque curve! On a different subject, have any of you heard that Crane Cams has folded and clsoed their doors in the past few weeks. Company may be bought out by someone else, but all 120 employees were let go. Sounds ominous for the go-faster hobby, what? Quote Link to comment Share on other sites More sharing options...
T120 Posted March 25, 2009 Report Share Posted March 25, 2009 That's an interesting looking item on the windshield divider.I'm guessing a compass.Are there any markings on it as to manufacturer? Quote Link to comment Share on other sites More sharing options...
Cpt.Fred Posted March 25, 2009 Author Report Share Posted March 25, 2009 you're right, thats a compass. completely dry, unfortunately... i'll have a look at the marks next time. found a closeup: no signals, no mirrors... but a compass and the antenna can't be unfolded in the garage completely because it's about 4 meters long. that ride's a boat i tell you:D Quote Link to comment Share on other sites More sharing options...
T120 Posted March 25, 2009 Report Share Posted March 25, 2009 ..Thanks for the closeup view.I hadn't seen one quite the same Quote Link to comment Share on other sites More sharing options...
T120 Posted March 27, 2009 Report Share Posted March 27, 2009 I had a closer look at your photo and it appears Hull is the manufacturer.It's a nice period item for your car. Quote Link to comment Share on other sites More sharing options...
aero3113 Posted March 27, 2009 Report Share Posted March 27, 2009 You can take that compass apart clean it and fill with I think mineral spirits and it should look and work like new. Quote Link to comment Share on other sites More sharing options...

Don Coatney Posted March 27, 2009 Report Share Posted March 27, 2009 I'll bet that just a good balance job on the lower end and a high cfm carb along with a competetive cam and stronger sprins could make one of our flatties turn 4,000 too. I magine that torque curve! Dave; I have spun my engine in excess of 4 grand several times. When I was taken for a ride by George Asche in his 29 Desoto powered by a 265 CI flathead he cranked his engine past 5 grand a couple of times. My friend Mark Hudson has a Mopar powered "Custom" pulling tractor and he has spun his engine past 6 grand several times. Quote Link to comment Share on other sites More sharing options...
Cpt.Fred Posted March 27, 2009 Author Report Share Posted March 27, 2009 sounds nice... now i only have to find the money for building something like that. nice tip with the compass, thanks! i will try for sure, it's a real crowd pleaser here because most people look silly when i tell them my car has navi.

Niel Hoback Posted March 27, 2009 Report Share Posted March 27, 2009 I kinda think that the compass is filled with glycerin, not mineral spirits or any kind of petroleum based liquid since they would eat the plastic. Better check with someone that knows. Quote Link to comment Share on other sites More sharing options...
greg g Posted March 27, 2009 Report Share Posted March 27, 2009 I believe Neil is correct. Mineral spirits work for levels but I believe the water for the compass rose is glycerin. You should be able to find it in small quantities at the drug stor or at places that sell soap making supplies for crafters. You could also make it throughthe cracking process involved in bio diesel production, if you wanted to strain, catalize, heat and agitate some used fryer oil...... the compass rose reference comes from nautical rookies aboard ship. Young helms men would be sent by the oficer of the deck to go tot he galley and get a gallon of water for the compass rose (that part of the compass which floats around to indicate magnetic north.) Failing that they would then be sent to the engine room for a bucket of dry steam. Thus their humiliation due the rest of the crew laughing at their nievitee pay their dues for joining the bridge crew. Quote Link to comment Share on other sites More sharing options...
Young Ed Posted March 27, 2009 Report Share Posted March 27, 2009 I'd be tempted to manufacture it by smashing open a couple of cheapie modern compass's 1 Quote Link to comment Share on other sites More sharing options...
