I saw one of those on eBay recently. What is special about them? Guessing they are rare, and for race blocks?

Not necessarily for race, but they were from the very first v6 production engines. The 1750. Same engine that had 2 less exhaust divider plate bolts and the 2 ram power trim that the oil ran through the lower engine mounting bolts.

Post a picture of the exhaust chest and of the sides of the block. Does it have behind-the-liner porting?

Any updates? I'm curious :D

is the "fat block" that folks refer to the 2.5 block with 2L sleeves? I've heard about those but never seen one.

T-Rex had an F1 2L. Steel sleave or chrome?

all 2.0 135's/150's (production mostly) from '91 up usually referred to as a "fat block".. its basically any block that looks like a normal 2.5 but is actually not.....

Back then, I think it was chrome. Someone set me straight. :confused:

I had one I sold earlier this summer. It was a 2.0 F1 Bridgeport and i was told it was nic. That's all I know for sure ! Lol

:thumbsup:

don't think nic showed up till '90/'91 maybe?.. my earlier 2.4 BP's were chrome... so that might/might not come inta play........
