I have a 1988 formula E, 49 cu. , don't know if I should rebuild her fast Fred style or find my self a 86-87 56 cu. for my 13' vee paded Delta.
what our your preference and why?
49ers pull nice, they last, thats what i'm runnin. on the Vee hull i stay with the stock rod size. i think i could win with ether one, the 49 or the 56er

Thanks for the reply f. Fred, I will stick with the 49 cu. , got to find me someone who can machine me some finger ports in eastern Ontario. It must be expensive to ship a power head to the state?
Thanks again Mike
machined finger ports are most lustful, i've done a ton by hand, always tryin to get them to look machined. if you add more timin to the center window of the exhaust port than the outer two windows she will have oval port quality's or a wider power band. thinkin i gots a shot of 49 machined finger ports. i'll look for it, thinkin it's good to know what it should look like
