I just put my 351w in my truck a few days ago and its still running like crap. Im suspecting a vacuum leak, computer issue, clogged cat, or timing issue.
- Vacuum leak - I used Black RTV to make my upper intake gasket because summit sent me one for a 5.0. Is this asking for a vacuum leak? Also didnt put on a new egr gasket.
- Computer issue - I reused my 302 computer which is speed density and the wrong firing order. I was told this didn't matter since its batch fire.
- Clogged Cat - The cat is rattling like crazy. Its a high quality bassani exhaust so i dont know how quick it should be bad.
- Timing issue - I set my timing to 10 BTDC pointing at the end of the triangular thing bolted to the timing chain cover bolts. is this the right mark?
So which one do you think it is? Thanks.
