I think I remember reading about it, were the .100-.350 lift numbers fat on those 346's?
From what I know and how well you can work those I'm assuming they are a more mildly done than your usual 330's type 906.
Some flow information on these 346 heads are in these two threads that cover some of the 80 dyno runs.................. 'Pop's Engine' another 440 on the dyno.
Cody has finish another set of 346 heads with spare parts we've had hanging around for many years and we will use them on a 450/400 we are making for our '73 Dodge Charger. And no, we haven't been able to duplicate the flows we have seen in 906 heads in others like 452, 346, 902 or even 915 heads.
915....wow....this just reminded me I have a set if 915's he mildly ported and I botched the valve guide clearance. A valve seized and bent on one of our dyno tests. I gotta drag those puppies out and repair them sometime. But boy is that storage unit COLD right now!
Just a couple of days ago he expressed some interest in maybe doing some more heads again. Then begged, "Please Dad, heads maybe, just let's not build anymore engines for people!"
