I feel like I've been beaten a dead horse on this one, and it's frustrating me to no end. I found out the delta cam I installed with the rebuilt head was entirely wrong. I talked to the company that made the cam and the said it wouldn't run right with the computer and fuel injection. I ordered a 268 torker cam from engnbldr which helped out a lot, but still hesitates on acceleration.

Would a stock cam be more lenient on timing?

I've micked with the timing by advancing it one tooth on the cam sprocket. It runs 50% better advanced like this. I can't get the dot on the cam sprocket at 12o'clock. Does this mean I have lost TDC due to head shortening?

I also adjusted the air flow meter to give it more gas and this helped also. The engine acted like it wanted more gas up to a certain point. The intake is sucking air like you wouldn't believe. When accelerated hard, the intake sounds like the exhaust off one of those sport compact cars.

I've had it up to 70 mph in 4th gear. It loses power in 5th gear and has a hard time going above 65. The engine does not perform like it did or should. It's running like it has water in the distributer.
