398 cubes seems like a pretty major mod, and AFR heads aren't exactly stock

haha, i was thinking the same thing. 398 cubes is a hell of a mod. probably at minimum a $4k mod.

Sig shows a 398, which is a 3.875" stroke and .040" over. You can turn off/on sigs I believe in the User CP.

Funny.. if this thread was entitled "who's heads flow 275+ peak?" there'd be a thousand responses .

When it comes to actual results & not quoted flow numbers.. there's not many out there who consistently make 400rw+ SAE... especially not with stock displacement.

Do some more poking around & you'll find a slew of "280cfm lt1 heads" on cars making ~40hp less than they should. Search around, you'll probably get more results than you can stand to read

I'm running a head and cam package from www.Advancedinduction.com

Just got everything back together and nothing is tuned, so I cant tell you what numbers it makes and how nice it drives.

But, I can tell you it has a bad ***, very healthy sounding lope. And I can promise you its goin to make better numbers than 99.9%..or more of the other stock stroke cars on this board....somewheres in the range of 425-440 to da wheels.

AI's prices are great for what you get (best heads out there), and turn around time is usually great, much faster than lots of others.

I must admit I have not re-dynod but before tuning we got 395RWHP and 426RWTQ UN-locked though an A4 and 12 bolt.

SAE(0.97CF) Corrected STOCK short block and hand ported LT1 heads.

not quite 400 but close.

I have seen many of Phils head packages go 400+

Just wish he would return my e-mails a IMs....

So Phil you have any clue on 15* heads on a LT1?

Eh, Ellis?

I remember an IM awhile back, but honestly I get dozens/day so sometimes I don't notice who's messaging me or spend the time to figure it out. As far as e-mails though, I haven't recieved any from you in the past few months... are you sending to my Ai acct. or the hotmail one in my profile? Odd...

As far as 15deg stuff.. eh, a clue or two I suppose .

Thx,

-Phil
