I would say that you need to line the crank marks up with the block and the cams gears with their respective marks, but I would also refer to a service manual. After installing the belt, you have to set the tensioner without letting the belt even slip one tooth—all it takes is a tooth for the timing to be off and cause the misfires. Go back and retrace your steps.

STOP—-get the service manual for your vehicle and see what it is suppose to be like. Do not risk closing it up and thinking it is fine—you could cause serious engine damage if valves meet pistons. Each engine has a routine for lining up timing marks during a belt change. Some engines require two revolutions of the crank in order to line up the cam marks—refer to the Service Manual for that specific model & engine.

Sometimes it’s easier to go back to basics….you have fuel, do you have spark and air? What do the plugs look like?

I had a 94 Z-28 and this system on the LT-1 engine uses a reverse flow water pump—essentially backwards from all past Chevy small blocks. This system is notorious for trapping air when you do a flush and re-fill. Chevy was smart (for a change!) and installed a bleed screw right around the thermostat housing. Make sure you have a new thermostat installed—DO NOT run without one since this motor runs based on temperature and it is critical to maintain the correct temp. With the car running, loosen the locknut and slowly back out the bleed screw until you hear air hissing. Close the screw when you get coolant trickling out. Do this a couple of times after it is warmed up to operating temp. Add coolant as necessary through the coolant reservoir mounted on the fender—it will draw it into the system as needed.

You could also drill straight down through the center and try using an EZ-Out bit to remove. Be CAREFUL not to break the EZ-out or you will have even more problems. I have drilled bolts and used a progessively larger bit until I could collapse the bolt or get it to loosen. Worse case scenario if you mees up the threads you can install a helicoil. Plenty of anti-seize on the new bolt!
