Thread: Intake question

Tweet

Hey guys, thanks for the input. Here's the plan. I'm going to match port and polish the intake. Mostly just for practice. Stick it back on, test & tune on Thursday night. Make decision on ride home.
Again thanks for being here for guys like me.

Theres a couple of good books that can help before you start cutting away. I dont think I would try "extensive" porting with out a good flow bench.

Sounds good RGTROUGH, its always good to practice on a part thats not up to par, just to experiment. You really have nothing to loose, Just remember the rule of thumb on polishing. You can make it as smooth as glass before the fuel touches the metal surface, after fuel is applied to a surface within an engine its best to leave it rough.

The last Ford I (attempted to) port match became obvious it was a wast of time. I got the felpro gasket, market it out and started on the C9 429 heads. I had an old offy intake the po had port matched to a felpro. As I realized how much material I needed to remove and looked at the intake runners I realized all I would have was a big enlarged section in the intake flow path where the head/intake intersection was.
I have no substantial proof but I always took the advice against the mirror smooth intake finish too.
