yea, thought that was pretty ingenious, but hell it worked awesome! ill actually be using it again to clean the SC housing and TB. gonna do a full rebuild on it and PnP it, might put a short snout on it and put a smaller pulley on it.

news today; figured out what my real compression ratio is! 10.01:1 was a lil much i figured, especially for the minimal work that was done.

so i CC'd my head today, and found the chambers ranged from 38.5-39 cc's. my head was milled .008", id figure the original size was about 40 cc's.

so with everything else, my static compression is coming in at 9.52:1. much more appropriate. i should be able to run 5-7 psi without a problem and put down a solid 260-ish at full boost i think. luckily with this S/C i dont have to run a BOV, do to the internal bypass valve. really its an ingenious design.

i figure my pistons will live for about a year if im decent too em, so i plan to get another short block, and build it for boost. shot peened rods, probably forged pistons...might look into that stroker setup, seems iffy. but hell, one more thing that noone ever finished! also, with that setup, i would definitely have the cams, and up the boost. have been looking for a beefier transmission as well, cuz god knows the w56 wont hold to more that 250 for long at all.

neway, sorry to bore you guys all with my 4x4 talk. but frankly all the 4x4 boards ive been to kinda suck...everyone gets pissy to easy. must be all the unfinished projects...just kidding!
