This is why I build my own carbs.

What do you build them from?

Plywood!

But only Marine Grade.

That's what I used to use too, but it got too spendy and I downgraded to pressure treated wood. Knock on wood, but so far no termites.

...I found the throttle response and mid range is great but the manifold I use lacks the ALL OUT top end over the 950 and Super Vic manifold I built the engine with. ...

Are you saying that one Holley 950 and Super Vic manifold flows more than a dual Holley 650? Could it be that the lower top end power is because of fuel curve?

Well first it is a custom built carb that actually flows more air than the old HP series 950.

As compared to the Super Victor intake the runner size of the PME dual quad intake is smaller thus on this 427 sized engine it has a bit less top end power than the race type Super Vic. Still performs well in the 2000-5500 RPM range though.
I built the carbs from the best 1850 parts I had and added the larger 750 base plates for a 650 type carb. They are in great tune!


Note: don't get excited as that is NOT the fuel filter in low left of picture...it's a PCV filter.

You're the man on this stuff.. You did a nice job on this.

Well there you go! If you have the extra coin to spend on the venturi job and you can't sleep without knowing what it could do with the modified 950....go for it. Otherwise I would leave it alone and enjoy!

it's going into a 69 camaro , turbo 400, 4000 stall converter, 4.30 rear gear and a guardian nitrous kit from induction solutions

Yep, those new plywood based modern carbs are also environmentally friendly too! Bye Cracky! Kick that spittoon over here!
