My SR flowed 280 after some porting & gasket matching 
How much porting did you do to it? was it more then mine? I would love to get mine to flow 280+cfm! Have any pics of the port work!

My heads flow 292 @ .600, but my cam only lifts to .565 if I recall correctly, so I was happy enough w 280 CFM from the intake.....the parts matched up pretty well 
Nice,,,is that w or w/o the base?
Here's some pics from my archives:

I think that before somebody just starts porting on these they should use a calculator like this to get some ideas:

you just might find that siamesed runners removing some of the length with not only pickup flow but also cover dips in a power curve or bolster topend, or low end etc...
you might find that you are restricted in the maximum diameter and need a LONGER or SHORTER runner (easy to shorten to hit another harmonic)....
hope my brief post makes sense, if not contemplate on it...

It's with the base, thru the TB

Oh wow, U didnt do much porting at all from the looks of it. What was done to the Base? If that ran 280cfm then after i port match mine and get thing liked up better i dont see how i can run the same or more! How much is it to have one flowed just to make sure im up in the 280+range?

It all depends how and where you port it to get the cfm. Just "hogging" things out can do more harm than good sometimes. Without really knowing what a motor will want its like going into it blind.

I don't know what current costs are, my motor was done several years ago. I'd check out some machine/race shops in your area. I think you might be looking at 285 ish on your setup if it's gasket matched well.

As I recall, Caboboy has a 406 CI or larger engine that dyno'd at more the 550 HP. As you can see from his pictures, he has gasket matched the holes in the plenum without any porting. The SR does flow well without much work....the original design was from Lingenfelter.

Alright i took some close up pics with a camera. All i really did to the inside of the runners was use a 40grit flapper wheel and smoothed them out good. Then i took the wall out a bit and opened it up to swallow the golf ball. Also tapered the edge of the plenum to runner area. I will be goin back to bolt the runners to the plenum and make the plenum to runner match up so there is no "shoulders" at all! Also guess i should try and make the dividers less "knife" egded...i might have to take the divider back another 1/4" or so to get the rounded tho.
