How would you build a wc puller?

He did it on a bridgeport. Bored to fit the sleaves, took counter bore out of top of block,we turned the sleaves down on the bottom .o26 gave sleaves. 001 clerance and pressed them in. I used lock tight sleave sealer. 9 years ago never leaked. We o-ringed the top of block, used a .050 stainless wire and copperhead gasket. I used big block Chevy pistons, 4.600 with a 1.24 piston height. The piston were flat top we took a little off top of pistons to back off compression some. It has 110 hp. I run 10 psi air pressure in tires, u want them to squat a little so the whole lug makes contact with the track not just the center.

How did your friend bore it? Does he have a engine boring machine or something else? I have a Bridgeport mill and am trying to figure out if I can bore with it. Its about 600 to bore a block and 1800 to stroke a crank around my area. If I could bore it myself, I can get sleeves cheap, and am thinking about making my own 4 5/8 pistons.
I was thinking about tires and why 38 seem to do better and what I have seen is 38 always get 3 cleats on the track. My 28 can to if I run low pressure. So if I can get the same bars on the track it seems like 28s should be able to work. Maybe I am thinking wrong.

15.5/38 and 13.6/38 I run the 13.6s more tho they are about a inch and a half taller then the 15.5s

Good luck finding a 175 cam and if u did pretty sure you have to change the oil pump also. I think a d17 gives you more rpms but you could just mill your gov weights down a little. Finding a rc rearend is not easy or cheap Id save your money for the motor. You could send your cam out to be reground for around $200 dollars. ive got a 240 in my wc 11:1 comp. reground cam, larger intake valves stock exhaust ported head, larger carb and it makes a honest 55 hp. I have high crop gears pull second gear till 5 thousand pound class then drop to first gear. Sometimes I win sometimes I lose.

No way a stock HP WC motor would pull 38's
