do a search on ski_dwn_it, he already has his jburnett built single plain manifold up and running on his 434.
If I recall there were at least two other guys on this forum who were installing these, (one was installing his on a milder (ie: close to stock) setup), they have posted their progress but I cannot remember their user names so you can look up the threads.
Hope this limited info helps.

I am building one too, but mine is a bit different. Mine is based on a Team G from Weiand. My app is supercharger too, so the actual flow isnt as important, no matter what I do Im sure it will outflow my TPI. Pics can be seen at Cardomain.com/id/sbnova at the bottom of my Vette page.

Second, I'm planning a 427 SB and want to know if your set up would be ok for it. Mostly street setup with mild cam but good heads and exhaust.
Third what is the current price and availability? Any pics?

Mine is finally coming along. For those of you who don't know, I swapped my super ram out for this. Still have the 74219 cam and stock (worked over) D ports. I still haven't dyno tuned yet, but I have driveability just about worked out. The more I tune with a wideband the stronger it gets at WOT. I would say it runs with a Super ram to 4800 and then out pulls the SR from 4800 to 6200. It did lose a little below 2500......but I don't blow the tires off as much anymore.....it's now actually a forward motion. I had to add alot more fuel to power enrichment from 3600 to 5200. I'm expecting a 25 rwhp gain over the super ram and really close to the same 375 foot pounds that I had with the SR.....just at a slightly higher rpm. I don't plan on keeping the 350 for much longer though.

You can put me into that small group. I am still working on sorting out why I only have 10" of vacuum at 900 RPM, and an off the line bog and backfire. It's been a busy summer so time to work on the car is at a premium. I have to get my azz in gear and get this settled before I go racing again........
Given my stock tune, and drivability issues, it still pulls like a **** above 2000 RPM.

You can count me in.
See my signature for results. So far the SR has been faster, but i'm running a stock exhaust which i believe is limiting my top end, so i gave up a small amount of low (low) end torque and didn't get the payoff at the top. Plus i haven't really had a chance to tune it at all. As a bracket racer, the SR is a little too hard on the tires making it difficult to hook up consistently.
The SP is a lot simpler to install, after the first time. I have an early version, and it took some work to get everything worked out, but now pretty straight forward.
btw....JEB is a solid guy to work with. Took the time to help me out with a few things and i wouldn't hesitate doing business with him again.

Yeah the stock ECM will handle your setup.
Jim is right. I have been bouncing back and forth between the MAF and SD system. Thus far the MAF has the MPH lead, while the SD has the ET lead. Although I should say that loosely, since really the MAF has both leads. The SD has the best times through the intervals, by a few hundreths, but nothing to write home about.
I have been trying to get further tuning on both. But as PA weather always works, come friday, it decides to pour down the rain!
I have decided to move from building fast cars to building a ARCs
