4 mill help

[slopoke]

I was wondering how much difference a 4 mill would make on stock drag ported cylinders vs a stock stroke with same cylinders. I know they will have to ported a little different but will I notice seat of the pants difference? I will be running stock carb setup (for now) and t-5. Is it worth the money?

If your cylinders are drag portrd then you won't be able to have them reported for the 4 mill. The ports would be opeaned up to much by the time they were lowered back down. (4mill crank will have the pistons fall 2mm farther down in the cylinders)

I know this I meant comparable. I have another set I'm gone send to herr. I just wanted to know if it is a big difference with a 4 mill vs stock stroke. Thanks

You won't be dissapointed with a 4mill, it will pull alot harder and you should be able to pull a taller gear.

I went from an mx port to a 4mill drag port tunnin pwk33s and T5s on both. It was a big difference. It was just as big of a difference swapping the T5s for CPIs.

Yes, it is most definitely worth the money. I think The 4 mils are the best bang for the buck.
