I'm having the same issue. I pulled the spout connector , brought the engine to 10* BTC, and dropped the distributor in with the rotor pointing at 11 oclock (about the front left upped intake bolt) and turned the distributor from there. It got me up and running but my car wont rev above 3k. I've got HCI but I have b303 cam. Hope it helps a little

Try jumping a tooth on the distributor till it evens out.

Read your instructions on the cam you used again, most cam in block motors require a timing advance to even idle. Should say in the instructions how much, but its normally just as easy as advancing the distributor

ECU has been programmed for 24# injectors (or calibrated MAF)? Do you know why it isn't running well? Too rich (my guess), too lean? Why do you think it's timing?

 

[Shifty Powers]

Who callibrated the ECU? Is it a chip? If you have the chip programmed for 24#ers and you have a maf calibrated for 24#ers it will not run right. You need to have one or the other. The ECU calibration being the better option of the 2.

Or if you dont have it calibrated for 24#ers, that is not helping as well. Also yes check the timing to see where it is. Its possible its off and may need to be bumped up due to the cam and such

A timing light is pretty much idiot proof. Stabbing the dizzyat exactly the degree you want takes a some know how and exp. Looks like a timing light will solve some issues here.:tongue3:

B303 cam gets lined straight up. It's not suppose to be advanced or retarded.

Op has a f303, while i agree you need to get the ecu calibrated it should still idle, even if its not well. [MENTION=21674]flashsgt[/MENTION] have you tried getting it calibrated for the injectors?
