i would begin to worry about piston skirt speed with a longer stroke and a shorter rod. selecting 1937-38 pontiac rods instead (which i could not find readily) gets you a 1.999 journal diameter which could improve the situation by netting a 0.3135 stroke increase. i purchased 9 new-old-stock federal mogul 1939-54 rods with slight water damage on e-bay for $9.99 (for the whole lot!). take-out ls1 pistons are commonly found inexpensively on late-model performance forums, i purchased new main bearings and new-old-stock cam (to regrind) very reasonably from Memphis Equipment. so far i'm into this cheap. if the welded stroker, cylinder head work, balancing, and what little machine work that i can't do myself and will have to be farmed out is the most expensive part, then i'm ok with that
