Building a Bandolero W/governor

[Nubs]

I had built some of these engines about 15yrs ago for a guy down the road that set his son up in a bandolero car. Now the son has moved on and the guy installed one in a pulling tractor for the last two seasons, now he asked me to build one with a few updates.
He wanted me to take pictures as i go so i thought i'd post them here as well

This started out as a stock 350447 type 1209-A1 code 9612411. over the seasons in the car i installed 23hp heads and a mid range cam 3,500 to 6000 rpm, the rules back then were the engine had to run the factory governor and carb. so pretty much anything else to make power was fair game, well kinda..

The new pistons are .010 over one cyl would not clean up so i had to sleeve it, then zeroed out the deck height, now the piston sits flat with the top of the bore @ TDC. this block had a +.013 deck height from the factory. the last picture was of the other cyl without the sleeve.

The new sleeve is pressed into prepared bore and then milled flush?

Good stuff, Nubs! Keep it coming.

Yes the hole was .002 small, block heated to 300ish and the sleeve was in the freezer. slips right in with some loctite 640 on the last inch, i left a .125 ledge on the bottom of the hole for it to sit on.

locating pins added to hold the copper head gasket in place, will see why as this goes along. this indicator works nice for finding center of a hole with the mill running.

Was able to cut in some larger stainless valves and still use the factory seats, opened up the bowl and runners also.







i use a marker to check as i go

I'm enjoying this thread.

Yeah me too!!

[Nubs]

This is how i go about opening up the bowl/seat, i'm sure there are better ways to do this but it has work good over the yrs.
this is a different head but same concept

[Nubs]

I'm waiting on some parts so i moved on to the exhaust problem, not sure what someone was thinking here but i found this 1 1/4 tubing for $18 shipped to the door.







some part numbers if your wonderin'

the rods were a $225 for the pair.



Pistons were $300

[Nubs]

Still waiting on the copper head gaskets so i setup some closed chamber heads for the bandolero HO in another puller that's in the shop.


I'm looking a get 225lbs compression so decided to o ring them

milled .005 to clean up


used a 18/20hp gasket to scribe the cyl location





cut the groove and tap the wire in with a piece of hard nylon, need to make sure the ends of the wire is square so there's no leak. .045 wire so the groove is .43ish wide and .040 deep. need to remember to add the .005 the wire sticks out to your total number for piston to head clearance including gasket thickness and deck height. total of .027 to .032 is the magic numbers. had to sneak the groove up a bit to clear the alignment pins

Nubs: If you don't mind can you tell me what Header kit you used on the engine in the pic ?
Thinking of using an off the shelf rather than Fab one up at the shop ?
Thanks

I have never found a kit that did what i wanted for the 14/20hp, i piece meal it.

1069 EC Exhaust Flange

1" OD 90 Degree 304 Stainless Steel Mandrel Bend - 16 Gauge - 1.5" Radius - New | eBay

the colletor is the hard part to find, this is 1-1/2 inlet but can slit/weld and made to fit the 1" pipe
Vibrant 10350 2-1 Merge Collectors- 1.5in. Inlet/1.75in. Outlet | eBay

Old school Bandolero setup done, 14hp closed chambered heads, 23hp valves and the Briggs aluminum rockers.
the 23hp intakes are .080 larger and the exhaust are .055 larger than the 14/20's, installed head studs to save on thread stress from head changes and added compression.
valve springs and retainers from EC distributing, good for 12K rpms

know his has nothing to with this thread but it was the last thing i had to do to wrap up this one. hoping to get the head gaskets soon... and back to the other one


These engines in the pullers run flywheels, seems that most run a 17lb wheel




This fella wanted one as heavy as he could get, carved one out of some 8", weighed 48lb after balancing
