  1. Hello 48p15, Really nice car you have there and I also like the wheel/tire combo. As a hot rodder myself I’ve always believed there only needs to be one perfect example of an original and the rest can be modified, that said it would bother my conscience to cut your car up but you only have to please yourself and everyone else can go you know where. BUT you came on this forum pretty hard almost like a troll, so the advice you get here might be limited. A lot of the guys you had some friction with are the hot rodders here. A couple of upgrades are Rusty Hope front disc brakes, the master cyl I’ll leave up to you. I kept the stock one with the check valve removed and my 49 stops great. Relocate the front shocks for a better ride, just do a search here to find many write ups. The 8.8 explorer will fit nicely, I have one in my 47 and they are tough. There was an old thread here where someone adapted a later GM power steering box even using the stock pitman arm, I hate rack and pinion steering so I would NEVER add it to an old car. Fatman sells dropped uprights but you have to modify your steering arms. Poise makes dropped super slide springs so you don’t have to run such a tall block in the back. Just an added tidbit and I really don’t want to set you off but I worked at Ford for 20 years mostly doing drivetrain stuff and I went through a lot of AOD, AODE, 4R70W and 4R75W transmissions and I’ll tell you straight up, they don’t even come close to a 727 in brute strength. Closer to a 904. The A500 and A518 overdrives are also light years stronger. Built lotsa those too. FWIW, Adam

    Electronic ignition again

    The problem is if you actually drive your vehicle and that Pertronix craps out, and it will crap out. You are stuck until a replacement arrives. If you don't venture far from home by all means put one in. If you do, buy 2 and keep a spare.

    Electronic ignition again

    No on the 6v you're better off sticking with points, much more reliable than Pertronix....

    Electronic ignition again

    It's not surprising to hear about another failed Pertronix module, they are junk. Before going back to points search slant 6 distributor mod here or Google. Add a GM HEI module instead of the Mopar box and you have an ignition system that's light years ahead of the troublesome Pertronix. Adam

    1940 Chrysler Windsor Coupe brake conversion

    Looks like it’s time to call Fatman for a set of dropped spindles.

    1940 Chrysler Windsor Coupe 1st project.

    I was always amazed how well the stock brakes worked until I had one too many oh $hit moments and off they came in favor of disc brakes. Remember, we are sharing the road the little Honda $hitboxes that stop really fast but we can do better. Drums were fine when all cars had them, times have changed and driving styles too. Biggest problem I see is it really does take the brake tool to get them right (very rare and expensive tool) so that's strike 1. Then you must arc the shoes to the drum, good luck finding someone to do that but it might just depend on your location, strike 2. Say you do actually fork out $800.00 + for the tool, find someone to arc your shoes and actually get the brakes set up correctly, they will work great but it's all down hill from there until you readjust them again. Strike 3 Any old vehicle with an unknown history should have the brakes rebuilt, for that money you could upgrade to disc brakes and have some left over for beer plus it will stop better every time, not just when the brake adjustment is top-notch. If you are building a concourse car, keep the drums and ignore everything above. Nice car BTW, enjoy it but make it safe.... Adam

    Stockton Wheel in California

    There has been several (a lot actually) posts on the HAMB about Stockton Wheel taking their money and not delivering. Just sayin...

    subframe swap

    Second gen Camaro is a better fit because of the front steer but it is a little wide. Not so wide that it’s unusable but offset wheels will have to be used or narrow control arms from Fatman. I went the Fatman route. Don’t let anyone tell you any of this stuff is easy, they’re either BSing your or paid someone else to do it. Just swapping engines is a fair amount of work, subframing Correctly takes time, skill and patience.

    1951 Fargo 400cid on Dakota chassis

    Why the motor plate? That’s a lot of engine suspended between the plate at the front and the trans mount at the rear.

    P23 engine timing

    Have to look closely for the marks, I removed my crank pulley once a few years ago and painted them. 2 other ways to time it... 1. Using a vacuum gauge to get to the highest vacuum 2. (the way I do it) Advance it till it pings under high load, lower RPM, back off till it stops pinging, back off a little more, lock it down. I only use the timing light to see where I ended up after doing the above. Fuels are much different now and some factory specs are worthless, timing be one of them. Adam

    What is the limiting factor on mopar flathead rpm?

    I’m not as familiar with the 25” blocks as I am with the 23” blocks. That said if I were going to have custom pistons made, I would use a 230 crank and 218 rods, pistons cut to 0 deck with a higher pin height because of the longer 218 rods. Then find a 201 or late 50’s 230 head to top it off. Adam

    What is the limiting factor on mopar flathead rpm?

    While you’re at it, use the longest rods possible and measure for zero deck. Adam

    What is the limiting factor on mopar flathead rpm?

    They will run all day at 3600 rpm. I cruise mine at 2800 which is over 70 mph. With the old gears I cruised at 3200 and never had any issues. Long stroke = high piston speeds limiting rpm Adam

    Dual Carbs on 218

    I went with the dual Carter/Webers From Tom Langdon and couldn’t be happier. No distributor or ignition mods required. See link below. Adam

    Dual Carbs on 218

    Your best bet is to keep the point ignition instead of Pertronix. Nothing wrong with points and if you have issues with your stock distributor such as a bad vacuum advance or worn bushings, you can still do the slant 6 mod just use a point distributor instead of an electronic. Adam

    Is there a lock washer on the crank pulley?

    It looks like there is a star lock washer on mine. Can’t say for sure if it’s original because the engine has been rebuilt but I think it is... you have to zoom in to see it.

    Dual Carbs on 218

    In Thrashingcows' write up, he ended up using the Slant 6 distributor gear as a spacer. Probably because the Flathead retainer broke. I was able to get my roll pin out and reuse the Flathead retainer and it all went back together with correct end-play and no additional holes drilled in the shaft.

    Dual Carbs on 218

    Yes, Dartgame is correct. Seems I've posted this link a lot lately but Thrashingcows did an excellent write-up on the Slant 6 distributor mod. I'll keep posting the link if it saves someone the Pertronix misery a good number of people have gone through. Keep in mind 12v is a MUST. I also perfer and used the GM HEI module from the 70's era vehicle attached to a heat sink from a late 90's blazer/K1500 seen on the right side of the picture below. Don't mind the 6v regulator in the picture, I use it to house my relays (horn, ign, fan) The car is 12v. I am still using a Pertronix 1.5 ohm coil I was given from a friend that gave up on the Pertronix after a few modules left him stranded. I have thought about going to an E-core .3 ohm coil I have for hotter spark but I've been warned it may become too much for the Slant 6 cap/rotor to handle but I have no proof. The MOPAR ignition boxes are troublesome. NOS ones are either no good or non existent and the replacements are overseas specials plus you still have the troublesome resistors and a weaker spark than the GM unit. Thrashingcow's write up and pictures should be in the Tech section.... Adam

    front suspension & rearend swap

    Look at Posies superslide rear springs. They come with reversed eyes if you want lowered springs or standard. Adam http://www.posiesrodsandcustoms.com/

    Dual Carbs on 218

    Just a suggestion. If you plan on staying 6v, stick with the points. If 12v is your plan look up the slant 6 distributor swap. Keep the Pertronix for the trailer cars or carry an extra module and tools in your glove box. Adam

    Need help , Engine misses / stumbles

    Thrashingcows did an excellent write up here I used a GM HEI module from a late 70’s car instead of the troublesome Mopar box and resistors. Parts are super reliable and available at any parts store if you are traveling, DWELL control is much better with the HEI module than the Mopar one. Better than being stuck with a broken Pertronix module waiting for a replacement. Adam

    Engine Timing for a D42 flathead

    If it’s a stock distributor it’s probably a Pertronix, check the vacuum advance. I timed mine at about 500 rpm. You are correct, marks are hard to see. I painted mine red to see better.

    Engine Timing for a D42 flathead

    I set mine until it pinged and backed it off a couple of degrees. Ended up about 5 deg BTDC. You didn't mention what electronic conversion you have, if you converted your old distributor make sure the vacuum advance can is not leaking. Adam

    Overheating. 210 in a 160 thermo

    For no other reason than to heat the intake manifold, mine now has a 5/16 line running from the rear of the head to the top inlet of the water pump, effectively making a bypass. Ran fine before I replaced the intake when it had no bypass. I’m running a 4 pound cap and I rarely see 190 on the hottest days, mostly 170-180.
