I appear to have a motor that cannot possibly exist. I purchased a really nice 66 Coup from an auction three years ago. It was sold as a 200 Cid except it turns out it is not. Last week I blew the head gasket between cylinders 4 and 5. No big deal. Pulled the head and started measuring everything while I was in there. The engine has Clifford headers, claimed a Delta Camshaft and a two stage Weber carburetor. Drive train is a Tremec 5 spd with 4.11 rear gears. The car pulls really hard, like set you right back in the seat fun so I figured it must be stroked or something to make it accelerate so hard.
Hahh. Bore is .020" over, no big deal. Block has five freeze plugs so that is a 200 Cid. The stroke, an impossible stroke, ready for this? 2.5". Read that again, 2.5" which equates to a 144 cubic inch motor. I have two professional mechanics verify I am not crazy, well maybe a little. So someone explain to me how someone stuffed a 144 crank with (4) main bearings into a 200 Cid block that has (7) main bearings (WTF). Oh and it gets even better, the head has the Hexagonal log which means it came off of a 250 Cid. 1.75" Intake, 1.40" Exhaust. I cc'd the head at 68cc. That gives me a whopping compression ratio of 6 to 1.
This thing should not even be able to run let alone go like hell. So what the heck is this thing? Curiosity is killing me.
Head E22E 8090 BB
Block 8Z D8BE 6015-GE
I can't claim I got these numbers exactly correct because some of them were a bit muddled as cast.
Captain Bill awaits your wisdom on this matter.
