[lucky]

I was thinking Ron said use regular 3 3/4 stroke pistons with a 4" crank for the pop-up setup, that still leaves the cost of special heads?
Guess I won't be building one unless could find some heads within reason.
Had a friend in about 1960 with a '32 cpe had a 3 3/8 X 4 1/2 popup engine,.
Red Cornett Summerset Ky built that engine and welded Merc crank and he proly made the pistons, can't remember what brand aftermarket heads he used.
Sure ran though, faster than my chev powered '34 pickup.
This is great stuff, keep it going.
Seems like he wanted a block stamped with Z?
