fuel injection swap - 5/7/2008 11:12:38 AM    SalikDDD   Posts: 457 Joined: 10/3/2007 Status: offline alright guys, i cannot find information for this but i want to know if it's viable without a cam swap. since the 289 uses the older firing order, swapping the ecu from a H.O. wouldn't be fine would it because it uses the new firing order which would lead to some problems - is there something i can do about this other than swapping the cam for a 351/ho firing order or what? can't i just rewire the distributor ? or something? :| ugh. _____________________________ 1998 Mustang GT - 1967 Mustang Coupe Post #: 1

When the right hand O2 sensor detects a change in mixture the PCM will adjust the flow to the injectors on the right bank. Problem is when you rewired the injectors, some of the right bank injectors are now on the left bank. Can you see what is happening? You need to swap in a modern cam grind. You may as well go ahead and make it a hydraulic roller and do it right. _____________________________ deadcarnahans (in reply to SalikDDD) Post #: 2

It'd be cheaper to go stock and swap to a roller cam. _____________________________ Who cares how much horsepower it has, all that matters is how fast it goes!

RE: fuel injection swap - 5/8/2008 2:15:24 PM    deadcarnahans Posts: 546 Joined: 4/29/2006 Status: offline You don't NEED a roller cam. Just get a good modern cam grind for the 351 order. A custom grind with 112-114 degree lobe seperation angle will work good with the EFI. Plan on new springs to go with the cam. _____________________________ deadcarnahans (in reply to SalikDDD) Post #: 10
