I'm looking for flow numbers (or file) for 193 swirl port heads for DD2K. I'd like to run some simulations with these vs. my ported 305 081's. If anyone happens to have flow numbers can you please let me borrow them?

Thanks,
Ben

U have flow #'s for your 081's? Can u send me a copy?

Keep in mind the 193's have larger combustion chambers than your 081's.

Hawk you have mail.

Mike,
I realize there is a 6cc difference between the two heads, thats what I want to do is weigh the benefits of one over the other. I actually read that whole article and the ones related before, but coudlnt find (and still cant) the stock 193 flow numbers. I see Dyno Don's slightly worked 193 flows but thats all. Or is that what you meant?

Thanks,
-Ben

I thought he menioned the untouched numbers as well in one of his replies. Maybe not all the lifts, but at .5, then mentioned they were pretty much the same numbers from .4 up.

Ok ya I saw that, got ya.

Was in a link within a link

""After doing the L03 thing I put a pair of those heads (193's) on a '96 Vortec 350 short block. It made 210hp & 330tq. to the rwhls. I then did some porting experimenting on them. You're right on the 168 cc's I had them flowed beforehand and was shocked at the results....178 intake 146 exhaust ( on a standard Super Flow) I was able to increase the cc's to 175 and the flow to 196 intake and 183 exhaust (didn't measure ex. cc's). I put them back on and went back to the dyno....250hp & 335tq The car ran 14.07 previously and 13.70 after, this was using an LT1 cam and 1.6 rockers on the intake. I know it had more in it but I didn't spend anymore time on the project. So in conclusion they may not be real good heads but they do perform with a little work ( I didn't spend alot of time on the porting, just roughed them out but polished the ex.).

Then later...

Don,

Just curious... what lift was that? The .450" lift since that's about there the LT1 cams lift, or was it at .500" lift?

It was at .500" but there wasn't much difference at .450" and it remained the same at .550"

I guess this would be a good time to ask. When I run my config on DD2K, for induction I am using 650cfm (Rochester Q-Jet). Would I use ' @1.5 inHg ' or ' @3.0 inHg ' ?
