there is one thing i forgot to mention about these,they will not work with a 2.8 throttle body due to the way the iac motor hooks up.these must be used with a 3.1 tb
What's the difference and how could us 2.8 guys change over to a 3.1 TB?
Nice work. It looks alot like the one I made about 4 years ago. They work. I have a rare and discontinued FDP 62mm billet TB made specifically for a thirdgen f-body 60*v6 on mine from a guy over in Sweden- factory TB is 52mm. My plenum volume is 4.1 qts- I sit slightly lower than yours by milling out the area where the shraeder valve would hit- thus I have no problem with hood clearance.http://www.cardomain.com/member_page...52_35_full.jpg
I like your TB, have you ever had that setup Dyno'd? I'm curious if changing the manifold and TB would help all that much since the heads seem to be the main problem.

I'm planning on fitting a Northstar 75mm TB on one of these manifolds , Dave is good at helping us out.
EDIT : HPE; I got those flanges made, if you need something PM me and I might be able to help (a good friend of mine has a CNC shop).

I have talked about TB size in the past around here. Going to a TB that large will cause a stuble or hesitation in flow because it is just too large for the draw of our engines. It will level out an work fine if opened slow and smooth, but crack that thottle open quickly and it will stumble. 65mm is about as large as I would recommend and even that is pushing it.Note for fact.stock 52mm tb = 308 cfm's62mm tb = 435 cfmsA built TPI V8 motor is running dual 52's and they are twice our displacement.Don't go 75, you will regret it. My opinion of course, but I am just trying to help you not make what I think is an expensive mistake.

If any of you guys still talk to him, ask where my TB, cam and manifold are. He was supposed to TIG some stuff for me in trade for my cam, but he kept it all.

^ A bunch of us are patiently waiting to cross paths with him at the track, but we haven't met up with him yet. Will definitely let you know when we finally do though....

^ I sent you a picture of him holding a sign of his new hang out, he's been on Fubar.com. I really wish you luck w/getting your money back from him, all I want is to get him in front of me... for a nice friendly chat lol!

Although my cousin Rob wrote this guy off awhile back, I still feel that the guy owes my cousin a very large sum of money. I really do hope that you get your money back from him John....

Re: new upper intake manifold testing done : available for purchase soon
^ From what my cousin Rob told me, the intakes were poorly made anyway. He never braced them properly on the inside, as the top center section of the plenum would cave downward whenever he put a load on it, you could even see it happening at idle if you looked carefully....
