October 20, 2003If i have to it shouldnt be to bad to just switch a couple injector harnesses...
October 20, 2003Is this a complete efi motor? If the computer comes with it just use it instead of the 302.
October 20, 2003Do they know that you`re wanting to keep your M5?

October 20, 2003Ya becuase i told them about having to switch the flex plate and flywheel and what not...Why....
October 20, 2003Id do that but if i do that then its programmed for an auto.
October 20, 2003Then wtf are they talking about goin from a 50 to 28 oz? If anything you want heavier, not lighter. Lighter is what you want if you race, not if you wheel/work your truck. Plus, as you know or should, a manual transmission flywheel is a helluva lot more than ounces. I`m guessing stock is probably about 30/35 pounds.

Over on the dreaded ftw. they say i need to switch from my 50 oz flywheel balance to a 28 oz and that my firing order will be wrong and it will run rich if i dont either switch the harnesses on some cylinders or buy a chip...... any ideas if thats true or not cuz im going up there sat to look at it and possibly take it home.
The pre `95 trucks are batch fire. They inject fuel to cylinders 1-4 at the same time and then 5-8 at the same time. Either firing order can be used, since the gaps when broken down by bank are the same. In the sequential injected trucks, you have to have the proper firing order, but the sequential EFI trucks already have the same firing order in the 302 and 351.
From my understanding using a computer from an auto for a manual doesn`t cause problems, but you can`t do it the other way around.
