i got a 94 z28 with a gen 1 sbc swaped into it i recently just got it tuned in. But its smoking prety bad and theres oil coming out of the exhaust on the drivers side it has true duals so i know which side has the problem im also geting blow by but its out of the valve cover on the passenger side i did a compression chech and and the cylinders all had 90 to 120 psi except for two on the drivers side 3 and 5 they had zero the car hasnt ran since last june but im wondering if im screwed or not any answers would be awesome

If 2 cylinders had zero you got major issues which is likely why it`s doing as it does. It could possibly have holes in the pistons which leads to gas in the oil which makes for a dangerous situation. Pull the dipstick and set a lighter to it, if it flames up quickly you have fuel in the oil. Either way no matter, you may as well pull it, It`s rebuild time.

X2 sounds like re-build time.
