Pissed Off So I put the stroker back together and went to start it and it wont start which i think might be fuel but besides that Im getting a knock... Not like a rod knock but more like a piston to valve but I dont think its that either.. Im just so frustrated with it guys...I dont even want it anymore I just put new ford 9 inch and mcleod street twin and so many nice parts and I just want it to run after all this work...I wont sell it ever but I really want to

Yea, take it from me. I burnt a valve and I got pissed during the dissassembly becasue I couldnt figure out why the head was loose, but wouldnt lift off the block. So I got a prybar (not thinking due to pissed off state) and tryed to pry the head up a bit. Next thing I heard was CRACK......the back corner of my bored and stroked block cracked off because I missed one of the head bolts (loose, but not out). Ohhhhh.....that was the worst feeling EVER working on a car. 1500 dollars later for a new clearanced block, gaskets, and bearings I was on the road again. So, the lesson I learned was STOP and think.
So, if you are ever upset with your car, think of that story and you wont feel so upset anymore!

its just that the only difference with the car then from before is the short block and the cam so theres no reason why it shouldnt start unless my ebay 30lb injectors arent working right and I dont have a tester to ohm em out

I have no idea why, but mine did the same thing, I got a fuel pressure guage, and lowered the PSI to the injectors, which much have been locked up, and it started and ran, like ****, till I changed the plugs to autolites, it hated the NGKs... In the mean while I still got high RPM missing and popping im hoping opti #3 this week takes care of. But anywho if you have an AFPR make sure its not set to high.

is the cam dial pin in the right place in the opti. it will do nothing but backfire if it is in the wrong spot. did this to me and pissed me of for hours trying to figure it out. Good luck.

There is only one hole large enough to accept the dowel on the back of the opti.......you would have to force the dowel rod into a hole that is too small to install the opti in any other position that the right position. It would be pretty hard to screw it up.
The cam could be installed incorrectly, of course.

You cant install the opti in the wrong position. So, if its an opti problem, then its probably a junk opti.....

I know this may sound dumb and I dont know a ton about the LT1 but had one for awhile. When I did my LT install I crossed some of the plug wires when i reinstalled them and all it did when i tried to crank was backfire like crazy. Im sure you have them on there right but just a thought.
Oh the lovely opti crap we love to HATE! I had similar problems with mine as it would start to back fire while driving every now and then, my ses light went bonkers, and that was indication of a mis-fire as well. You can laugh at this as I have, we took the motor apart twice! 2 1/2 months later and it was the opti the WHOLE time, we cleaned it the first time, and made sure it was in correctly, and when I started the car uuggghhhggg the mis-fire was worse, like the car had an upgraded cam, shaking and mis-firing, that was a sad day indeed. To think the opti can cause all those problems....lesson learned if this ever happens again, and this is opti #3 for me as well. BARF!
