Tighten down the Rockers a little bit. The way the OPTI goes in pretty much makes it perfect timing if it's in the right position. You can't really mess that up.

did you replace the tb too? i know when i did my h/c i put on a new tb and i had to hold the gas a bit to start it. im assuming something with the iac and the engine is choking while its being cranked

If the Rockers aren't in proper adjustment, then it won't run. I made that mistake, they were too tight, and it kept backfiring and wouldn't run. His are too loose, not letting enough fuel in, and I can back that by the fact that he said that they are chattering like crazy.

prob wanna upgrade to a lt4 knock module..with rollers the lt1 knock module thinks its getting a lot of knock when its really the rr's so it strarts pulling timing. just an idea

Definitely sounds like your rockers are out of adjustment. Did you adjust everything correctly at zero lash with the proper pre-load?

If you get the rockers set, and still no start you either set the timing chain wrong or the opti is not on right.

no it starts if you floor it then it will die unless you play with the gas

MAF maybe, but I am still going with the Rockers from what you said earlier.

Did you degree that cam when you installed it?
Also, double check your plug wires and make sure they are on right.
Check connectors from the wiring harness and make sure they are on tight as well.

sounds like its crosswired or possibly rockers too, double check your wires especially passenger side.

Did you have trouble codes before the install? If not I'd say your wasting your time changing sensors.
