Can someone tell me what a 2.5 block stamp pp stands for? I know someone had a chart identifying all the performance blocks but I cant find it again. Thanks

PP was a 260
edit. misread.
EE were the early 2.5 200’s with the small exhaust chest
How about a block stamped kk. I have two blocks that im trying to figure it out
You got me on that one. Never heard of a KK
Just last week
Kjdoo4 was asking because of this crazy motor I picked up. Not sure what it is? Its a big bore with 3.640 bores with weird o-ring steel sleeves.
Thank you for all the help guys. That was the image i remember roadkill. :cheers:
wow!.. someone was really gettin' serious with that one...……… :eek:
maybe for tha BIG pills.
Looks like something Alex Hledin did years back. I know he built some big bore bridgeports with that bore diameter
Looks like sumone was building there own custom merc. Which 2.5 had Bridgeport exhaust if any ? And o ring ??
looks like based off 2.5 with dowel pin, off chambered heads, 2.5 style pistons?.. only 2.5 I've seen was a "Z" port.. but with tha guy Eric mentioned it aint no tellin'...
If I’m right about it’s origin it’s a 260 block that Alex added the bridges to and used an OMC based piston. They made big power but the bridge was obviously prone to overheating. I always wanted to try one with methanol, way less likely to get hot enough to distortQuote:
