hey guys! spent last night trying to figure out exactly what all i have here, and i have reached a point where im going to have to ask for help from the more knowledgeable guys! from what i have found out, the block was cast in 75, but was placed in a 78 motor home, and from my understanding, which is pretty limited here, the motorhome engines came with kind of a wimpy cam, and low compression pistons. well this is where things start to get wierd. the exhaust manifolds are HP b-body manifolds, and the pistons from what i understand are not the low compression ones based off of how high they come at TDC, and had aluminium valve covers. either this was a projuect that was never finished or someone had a screaming wini camper. anyone have any insight here? block casting number is 4006630-440-7.
