SBC Bowtie phase 2 head question.

Postby JODY » Tue Dec 01, 2009 10:25 pm

I purchased a Camaro with these heads on a 377. I'm about to have the engine freshened up and to see what all is inside.
I was wondering what kind of flow numbers some of you guys have been getting them to pull. I do know the heads were port and polished by Larry Meaux some time back but there is no identifying marks other than his name. The heads are ported out to a 1206 gasket.
Just trying NOT to spend the money to have them flowed.

Larry,

Thanks for looking and responding.

The heads are cast iron.

I bought the car from Chad Noel. Charlie Stelly from around the Arneauxville area built the engine sometime last year he said. When I asked him about the heads all he could tell me was that he got them from a Keith or Kevin Broussard. I did find a 9 stamped on the end of 1 of the heads. The heads and intake have your name ground on to them. I wish those guys could give more information about them.

Would it help if I took a few pictures of them?

Right now the car with me in it weighs 3107lbs. I have ran a best of 10.77 @ 126 so far. Still trying to get shift points and launch rpm figured out.

i found some of the History->
i originally Ported them for Scott Segura's Dragster

then Keith Broussard bought that Engine w/those Heads
put it in his 1st Dragster

then Keith sold that engine to Gene Courville
then Gene Courville sold it to Charlie

Charlie sold it to Chad Noel

Charlie told me he ran 10.50's w/ stock 1050 Dominator

i'll try to find those Flow Numbers now i know who they were for
originally but its been 15 to 20 years ago ?

knowing Scott..they were just warmed over Bowl Ported mainly
not really Ported

Larry,

YOUR THE MAN!!! Thanks a ton!

Yes, Chad told me they had the car running 10.50s with a 1050 on it... right now I have a 950 HP that we just started tuning on before the winter break. It has a little too much thrust bearing walk for my taste and they couldn't remember the exact cam specs. So I'll get bearings and rings put in and some new valve springs after I find out what cam I have.

Plan on putting a small plate kit on it and have as much fun as possible.

Thanks again for looking into these heads!

Pictures of #034 1st design

has thinner chamber walls , and flat outside, no bulging like
the 2nd design upwards, that bulged out the casting
to get the chamber walls thicker and keep water jacket circulation

Image

Image


Compare to 2nd design and newer versions

i guess you could consider them Phase 1


here's 2 more Pics that i took at Brodix Foundry while visiting,
JV Brotherton told me not to show or tell anyone,
( but its been a long time ago ! )
i happened to see them on a counter, so i quickly snapped
a few Pics....but he said keep that to yourself,
you weren't supposed to see that !!

then he quickly put the head away in a drawer ! :)
