Singal plane help need guys..
I think if i ever went with a different intake then stock i would pony up and get a fabricated one. With my turbo setup the intake isn't near as important as it would be otherwise. I dont need to spin my motor past 6,200 =]
Here is a single plan elbow for sale, its already tapped for vac lines. https://ls1tech.com/forums/showthrea...90#post7970190

There are a few "Ram Air" type manifolds out there similar to this:

The price they quoted me was $750. After factoring in that, plus the extra fab work/plumbing you'd have to do to run coolant through it on an LT1, IMO it just makes more sense to stick with an aluminum manifold.

Thanks for the warning. I was hoping that since he listed part numbers he had the 4150 flange and it is. So I'm going to fill the bolt holes in and redrill the flange mounting bolts. This way I can turn the elbow so it faces the front of the motor. It is taller then what I made up. So i may have to mill the flange down some or have the spray bars put in the elbow.
Do you recall how tall your manifold is? From the bottom flange that seals aginst the block to the carb flange?
I would like to know if this intake is taller then what you guys are using. It measures about 6.5 inches.
Thanks Mike

While LT1 guys are shelling out all that cash for custom made parts
Wtf you would think by now somone would make a affordable manifold by now
when I shift 3rd gear at 7200 it feels like I hit a N2O button

Are you single plane guys using the 4150 style or 4500 style flange on the manifold. Just wondering if the 4500 has a larger "throat" or entrance to the runners that would be of benifit.

All motor here.
FWIW, that is a converted SuperVic, not a Vic Jr or Vic E. Note the carbon fibre filler plate below the runners. The red manifold in another post has that feature also. The heads on this one are also VERY special. The S'Vic runner length helped make the power required by the customer.
I would be interested in a good back-to-back comparrison of just the manifold swap. Everything I have seen is on a whole new engine. The NHRA Super Stock engine builders I have talked to say that is not the way to go.
If I get time I'll probably try one next year just to see for myself. I had Hogan make a sheet metal intake for my Super Stock 350", didn't cost much more than this swap, and everybody swears it would blow a single plane away. If I can get my hands on one to test I'll find out.

FWIW, the black and grey single plane engine shown made excellent torque from the low 2000s to the very high 6000s. It was for a street sleeper F-bod. Over 1.5 fwhp/cube with almost no lope at idle. The heads, manifold and cam worked well together. The engine cost a LOT.
[edit] BTW, it's a 396. 1.5+ * 396 = ....
