My 2001 Cobra has 100k miles on it and the short block was replaced 3 years ago with a
KarKraft Aluminum short block.

Car started up and sputtered down and died. White gas smelling smoke was coming out of exhaust. Fuel and water is mixing some where.

-No water in Oil
-Coolant is fine
-Nothing leaking from underneath
-Car not overheating (Well didn't give it time to)
-No Knocking or obvious noises coming from engine.

Nothing up to this point gave me any indication something was wrong.

Im going to do a compression test in the AM.

What is the likely suspect?

-Cracked Heads
-Head Gasket
-Cracked Block
-Intake manifold Gasket

Looks like it is the trusty right side head gasket. Ill be swapping it out this week and taking the Heads to the machine shop to get resurfaced.

Engine Suggestions on an engine rebuild. Stock cam/GT40Ps or aftermarket on both for a fun weekend driver?
