Big Inch Smallblock
I’ve seen someone’s report on them go a bit past 330, IIRC.
Shady Dell? I forget. The W2 if carved to the high heavens will get crazy numbers. IIRC, Dick Landy carved ridiculously huge rectangle ports. It’s porting way beyond normal.
From a been there and still doing it guy. Thanks for that reply.
my W5’s were the first set Ryan( Shady Dell) ever did.
Brett actually, from what I understand, did part of them and Ryan copied the rest.
kinda interesting, those heads ultimately ended up on a very reputable bench( Best Machine) later on, and another set, done the same way, ended up on another reputable bench. Very well known guy
on both those benches, both sets struggled to get over 300.
that said, mine ultimately ended up going right at 140 mph in East coast mineshaft air, at 3220.
that is a VERY honest 700 horse.
Moral to the story, flow numbers definitely aren’t everything….at all
edit, those W5’s were opened up such that a few of the spring cups were so thin Chuck at Best Machine was able to poke holes with a pencil.
thankfully, that got caught… running a 700 lift roller at 250/600 it wouldn’t have lived but a minute or two..lol
