Hudson, did you increase the pressure/volume of your oil system? Also did you do any sump mods? I'm thinking of building a mains girdle that doubles as a windage tray. Also looking at plumbing an inline filter & cooler where the pump mounts to the block posibly on the pick-up side creating a by-pass in that gallery. I may have to increase pressure incase of pressure drop because of filter/cooler.
Hyperutectic pistons are the way to go as opposed to forged. Pistons start off as blanks so a manufacturer should be able to make pistons out of something of a similar size/shape etc. I found some later long motors had 3 ring pistons which are an advantage. My father has Continental pistons in his 230 & had to have the crown skimmed & the bush resized to suit the smaller pin diam.
Also been warned off chrome-moly rings, someone else may have had some experience with these.
Pop-up pistons would be the way to go but I fear there isn't enough meat above the combustion chamber & it has a cross type brace to support it. Knew a guy that did & his head acted like a pump. You can get your bits sonic tested or x-rayed to check for thickness & material inconsistancies.
Had a look at all my 250 blocks & couldn't find any sleeved. I've got marine,industrial,truck & late car & surprisingly enough they're all either standard or at worst .020" oversize in the bore.
I'm going to run twin 94's on an Offy manifold(wish me luck).Also why do most of you use B&B carbs as opposed to Stromberg 1 barrels ? Somewhere I have some flow numbers for the Strombergs.
Anyway something to chew on & at the rate we're going they'll reintroduce the flathead with all our improvements !!!
