    Had a 225 in my 87 Dodge D100 pick up. It was gutless with all emission parts intact. After 150,000 miles it came out and a mildly built 318 went in. Now the truck can tow and go.

    I ran on in my 48 dodge truck for years before i could afford a v8, never let me down. Only issue was typical cracks in manifolds, i got lucky and found a NOS turbo setup made by Mitsubishi that i ran until the v8 swap. Still the thing only made ~160hp. *memories* have fun!

  3. I usta work for "the city" and we had street sweepers with 2 engines. The engine for the sweeper brooms sat high in the machine and was constantly running in heavy dust and dirt....they used MoPar slant 6's. We changed a lot of busted slant 6 motors. They all threw rods and broke the block at the pan rail. In all fairness, I don't know any engines that would live very long on those conditions.
    I also had an old Korean war M-37 Dodge Powerwagon with the flathead 6 as my service call truck. It was governed to run about 60 MPH and I gotta say that old flathead had plenty of power. I used it to tow stuck vehicles from time to time and in low-low it would idle and pull 1 ton trucks out of ditches...sometimes in snow.
    I'd leave the slant 6 for a lightweight vehicle and use the big flatmotor in a pickup...but don't rev that flathead. It'l break.

    My slanty.... Holley 4 BBL, I made the headers, and lots of other modifications that I did over 20 years ago. The car still runs after all these years! Awesome engines for sure.... I dig the your roadster. That air cleaner is really neat...

    Great car snd engine Jack.
    Got any stories to share about spanking V8s?
    Light car as yours is with a slant 6 on roids gotta go like hell.
     
  9. The plastic distributor drive gear shreds itself and ends up in the oil pan. One of the first things to check on a sudden "crank, no start" condition. Pull the cap, crank the engine, and the rotor just sort of sits there and wobbles around a bit. Fairly cheap and easy fix, though.

  10. I don't know if the question of sludge has been answered but back when that motor was new there were several brands of oil that had a high paraffin content. They would sludge one up pretty bad but still lubricate the engine. I would clean it up, put it in tune it and then give it a good flushing after I got it running. If the engine is h shot it can still be removed and rebuilt.

    The plastic distributor gear ages, cracks, then fails. It's the same gear as a 2.2L four cylinder. I always try to have one just in case...

    I have beaten stock V8 302 Mustangs and the "Pre-LS" Camaros that were virtually stock. The mileage is just under 20 MPG. The car can and has gotten up to 150 MPH according to a ol buddies Stingray. But for me, it's just a fun car. Win or lose, it's just a slant six.. Right? I don't put much emotion into it, I am just amazed that after 20 years of abuse, the damn thing just keeps a going! LOL

    I would be more concerned about the oil pump gear. From what I am reading nothing but troubles with new cams and oil pump gears taking a shit.

  18. Well I have owned a couple of slant 6s and been real happy with them. Never owned one that I could claim was a hot rod 6 but they ran well and pulled good enough for what they were. I think you would be real happy with one in the Fargo.

    This is very true, when I removed my Purpleshaft cam, not only did it chew up the distributor gear regularly, it annialated my oil pump gear. I sent in a stock camshaft core to Snyder Racing Cams, and they ground me a cam to my choosing. I have had no problem for 15 years now....

    If you change to a slant you will have to change your name to slant six fix!

    I have a 59 230 looking for a topload of some type. 30s car type I.ve heard is what i should look for. Going in this. I have looked at a pilothouse and I think I could use the big bell housing. IMG_2558.JPG

    I've run 218's in cars and 225's in swathers and I still think you'd be further ahead with the 265 in your truck. OHV's will probably give you more HP, but those flatheads are brutes for torque and I think that will give you more useable power in street vehicle. In stock configurations I would expect the newer motor to run longer between overhauls, but if you improve the oiling in the flathead, that may not be true any longer. I think if you were going to do the work of swapping to a slant, you'd be happier with a 318 for the same work.

    Thanx Baron and yes a 265 stock has similar torque and HP than a slant.
    They are 120 hp and lower end torwue 228 ft lbs at 1600 RPM
    It wont be stock hotter cam.dual carbs and headers.
    So maybe a 150 to 160 hp motor.
    Easy swap too..
    LA 318 nah like em.but no
