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

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
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'

Pistons were $300
