Blo---By the looks of the front end of that car...... I'm gonna say you were expecting more than 11.20's.
Any idea what it weighs?
Brad, didn't those intakes basically have MW sized port runners that were necked down to std port openings at the flange? Or am I remembering that wrong?
I think I only tested two motors on the dyno with one of those...... Yours and one other. As I recall yours had some work done to it, but I don't recall how it compared power-wise to the others. The other motor that I tried one on the intake was ootb, and it was down on power in the lower and mid-range, and had a narrower band up top where the big numbers were.
I would think the spacers(mounted and blended) and a new TF intake would probably be better, but how much better would be the question. I would think in a "race" application, the heads opened to MW size, with MW spacers would be in order and either an Indy or Super Victor manifold.

It weighs 3,150 with driver.

Brad, didn't those intakes basically have MW sized port runners that were necked down to std port openings at the flange? Or am I remembering that wrong? Correct, which goes to my comment that the Stage VI intake was really intended for a MW 4500 build. I think I only tested two motors on the dyno with one of those...... Yours and one other. As I recall yours had some work done to it, but I don't recall how it compared power-wise to the others. The other motor that I tried one on the intake was ootb, and it was down on power in the lower and mid-range, and had a narrower band up top where the big numbers were.
My Helgeson-ported intake made more peak HP, although only by a couple, than every other intake we tested that time. However, it also had a big dip in the torque curve under 4K RPM that the other intakes didn't have. I think it was too big in the plenum and had too much runner taper for a standard-port 440" engine; modified like mine and used with another 50 cubes and it might work OK for this 500 crate combination.

It weighs 3,150 with driver. Race weight? Or 3150 + driver? I was hoping for mid 10's Obviously it's not that hard to go mid-10's with a 500" motor in an A body.....although at the same time I'm not so sure that just replacing the heads on the motor with those CNC ported ones will be enough to get you from 11.20's to 10.50's without a few ofher changes too.

Yeah, that's with me in it. I'm sure with some knowledgeable suspension tuning and this head work, 10.50's are easily obtainable.

Dwayne,
If a worked set were to be found on the cheap, is there a substantial gain to running an RB intake on a B block? Or just skip these and run any of the other good choices out there?
Thanks
I want my fair share

IMO, they would have to be priced extremely wallet friendly, and be basically "done" by a reputable shop before I would even consider them.
They only make any sense if you already have them, and/or can do the work yourself.
There are just too many other options out there now to make stage 6's an "attractive" choice these days.
