No undersize here, bought a bunch of 3" main brngs for ols mtr{think was #1 from 303} the next step was going to be a bunch of 110-18 rod to build up mains and rods to a 4.5 stroker crank, nobigger prject than doing a rough forging. have eng dsg book that mentions that a flat crank doesn't result in smoth balance v-8's are known for, usually found if short stroke engs. my call to Arlin Vanke saved me lots of time & trouble{ friend just saw him @ indy swap meet, so he is still kicken} Wanted flat crank for internal bal on stroker,and even out load on 2&4 mains, which are the weak point in v-8 that gets used a lot for brake i.e letting off going into corners, wanted 3" mains and hemi rod sizes to increase journal overlap . There was a fad a while ago to take 460 ford cranks & cut to sb chey size {2"} to make stroker, most only lasted about 5 pulls in pickup, think everybody got over that one, well not everbody, a IH crank showed up w/ similar trick only better, lets use a real narrow bearing from IH trk v-8 I didn't evenwant to grind but they already had a set of billet rods made{ a couple of pulls & lots of bearing wear-go figure} any how #1 throw was already .025 ahead of back throw, they said guy that did crank had no way to index ?? maybe . anyhow to add to problems they bored out dry sleve to put in big wet liner, but could't block rock cuz can't get cam in or out with liners in place, had to run long allen bolts from bottom of head bolt holes to bottom of water jacket to try to hold head to what was left of deck, made a set of billet pistons as rehashed cast case pistons only lasted a couple of hooks ,that when they discoverd the rod bearing problem ; after all this rambling, it{IH} made a couple of pulls and is still in one peice= amazing what you can get by with ;at least for a little while.
