Question for Tractor Vet

Below you mentioned using 806 gas pistons in an H motor build. I’m contemplating a similar adventure and was wondering if the wrist pin fit and if you had to get inventive with rod length.
Thanks in advance

Lengthen them a 1/2in
350 pin is same as 806.
Use a late model h block but use std bore 806 piston
I’ve used 806 lp high alt pistons up to 6 in stroke
Fun n powerful

WHY , no guts no glory , i think we got enough compression like i said you could NOT hold a compression gauge in the plug hole and not even Barton the Animal could and that boy could hand carry SIX 150 wheel weights like caring a lunch box , hand load a 55 gal drum FULL into the beds of a 73 F250 4X4 setting on big tires twist the 3/4 drive off a 3/4 S&K ratchet with out a cheater pipe one handed . Go big or go home . Only NOTE TO SELF on going BIG of things never to do again on going BIG was Never go with a 7 and 1/2 inch stroke on a M M . Bore them into the water jackets and bore somemore then find something to fit in . we have gone as wild as put your hand in #1 hole and go all the way to #6 and never touch anything and make up sleeves to fit . Built several DUMPSTER engines that everything other then gskts and bearings came out of the bottom of scrap dumpsters at Cummins Mack and Detroit . Gskts Custom made fire rings installed in the top of the sleeves and groves in the heads .

Good god , we built that one some 25-30 years back and i can not remember if we made bushing up for the rods or not . Machine work we done at a friends shop . And Dick passed away about 15-18 years ago . Just wished i could have bought him out , What a PLAY ROOM with all the machines he had all the latest and greatest , there ya could work on a 3 Hp Briggs and strattion or even a Page drag line engine , 1710 Cumming had the only true LINE BORE that ya could do up to a V 16 Bore and engine from 1 1;/2 inch up to 16 inches . The only machining operation ya could not do there was grind or weld a crank. or cut a cam . Dick and i went way back together like back to 1962 He was five years older then me . We both like a challenge as we both like FORDS and we both set out to make FORDS RUN and did a pretty fair job of it .

Lol I did! And definitely know what it was like with them plug gauges. Shoot, one revolution and it was at 230 first pump! Even blew rubber hoses but got 310psi reading.
It was an h block bored n wet sleeved. Held up for 6 hard years
That ol h run with molines lol beat em too!

I’m not advertising but can bore n weld stroke cranks and make own rods. Just, not old enough in age yet to have the real good worthy knowledge yet. But had fun pulling!
I do have a 169 making near 60 and it’s all ih inside and no lp head. I did not build it, my dad did, he’s passed on and that’s the way it is.

I’ve got a line on a 300 block
I’m currently running an H bare block with 3/916 pistons so it’s 169ci now. Have a 300 head and carb on it and it runs good and has for a long time. Helps having 36” rubber on it too. It’s just getting beat up on by some hot ACs and Oliver’s.these days. My grandson is getting hooked on this disease and I want to keep him competitive.

Lol this could get real technical here!
Most Allis are 226 to 240ci in pulling, there’s bigger but that’s parts bought normally as sold on this site it’s a mix match n get power.
Oliver’s, who knows, n leave it at that!
Cover your bases, hitch, proper balance, tire pressure. All are adjustments to get more distance.

Well If you don't mind the color of Pirie Gold and ya want to have fun knocking peoples socks in the creek from 4500-7500 Then ya need to Build a M M Cummins , Allison M , J D A old style Like my Accountant and i built from the bottom of scrap dumpsters , Everything came from the bottom of scrap dumpsters EXCEPT rings , bearings and Gskt. . We build a M M U . Crank and crank case were good Blocks were Junk busted into the water jackets on the inside but not cracks on the outside. A close friend was service manager at the local Cummins shop and let me go dumpster diving and i came out with 6 855 sleeves that had 900000 miles on them , next stop was down to another friend and got 4 farmall M rods , my accountant called one of his BUDDY'S that played with Allisons and got 12 .060 over used pistons then he got 8 old style J D A valves and made a call to another one of his friends in Texas and got two 4210 heads bare FREE and a large 4 cylinder intake . Crank came out and took a ride to the west side on In. for a little welding and grinding so did the cam , Block went to my buddy's for a trip thru the line bore and a decking . The broken jugs went down the road from the shop to a machinist along with the JUNK sleeves and the Cummins sleeves were made to fit in the junk blocks once they were installed i welded them in at the bottom . When the crank and cam came back the jugs were placed on the crank case and back up to the boring bar and everything was bored off the center line then decked to the center line . then came the head work got the valves in then off to another guy that had this new Mill and a flow bench and let him do his thing . Once the flow work was done it was on to C C the heads . A little magic from me on a timing curve and stuffen all the junk pieces into this package a trip up to a Mil . salvage yard and a walk back thru the old dust warehouse with the old guy and the dropping of a fifty dollar bill for two 3 inch Bendix carbs new in the box from WW 2 along with a dozen carb kits throwen in and some more bench time once all was done and first run up on the dyno at 250 Hp at 1870 RPM and we COULD NOT Stop her and came real close to flippen the Dyno over . We ran 4 classes with FOUR different drivers , I ran it in the 6500 class and my accountant ran it in the 7500 and two of his friends ran the lower classes as Sam was the onlyone that could make the 4500 # class with his skinny little donkey . In the 45-5500 if you really wanted to make everyone mad you stuffed it in ROAD gear and went for it and at 75 feet she would give your the quiver in the seat of your pants pick the ft. end up about a foot or so off the track drop maybe 50 RPM and it was going to be a gate shot in short order . We NEVER tried to be first puller and prefered to be mid way in the pack . Then when you hauled the mail out the gate you already made a statement to the ones that THOUGHT they had a bad tractor and NO pull offs required . For two years all four of us were points champs .Mikey and i had UNDER 3500 in everything including the tractor and the fiber glass oil pan and top transmission cover wheely bars and weight brackets all made out of NEW ALUIM. Our closest competition had 29000 in just the engine so we heard and he was always 50to 75 feet BEHIND . After the second year closed we sold it to the comp,

I really enjoyed reading that Tractor Vet! Have a great 4th!
