prting setup help pleas

[Sandfrk33]

My stock cylinder 4 mil is running 340 mains. I've wanted to try a clean up port myself. Nothing drastic, just better flow. As long as you don't change the durations, I'd say go for it. Have you done any porting on an engine before? Helped my neighbor port the heads on a vw engine. I thought it was interesting. Good luck

Yes he's running stock carbs. It's listed in his sig. Your question asking what is the duration is why I'm saying don't try this yourself. If you don't completely understand what your doing the only thing your going to accomplish is fucking up your cylinders. I know one person here said go for it, but it aint his shee that's going to get fucked up it's yours, so your the one that needs to make that call. Again my best opinion for you is to find a set of cylinders already set up for 4mil with pistons and rings included. There is always some running around on here for sale. Once you have a properly ported and set up topend there to compare then I would say ok if they get fucked up it really dont matter. And as far as jetting I promise you that if your running a 4 mil on 280 jets its most likely lean and your going to burn it down. Good luck with all this keep us posted.

If you think that thing rips now throw a set of T-5s on that bad boy and see what it can really do.
