so, I rebuilt my 95 cobra engine, now a 306. the original 351 HO camshaft was not in good shape and I was unable to sort a replacement. I did have a spare E303 laying around so I put that in and wired the sparkplugs for a 302 firing order. the car now pops and is down on power so I am assuming the ECU and the camshaft are not communicating. I see two options, replace the camshaft with a 351W roller or replace the cobra ECU with a 93 cobra ECU that I have. am I on the right track here?
