Thanks Shawn. I don't believe we even tried with/without the spacer. We dynoed 2 BBC's that day. We've seen over and over that a 1" spacer is worth a little power on these types of engines. Some of the best spacers we've used are a 2" tapered, and a two piece 2" anti-reversion setup from Reher Morrison. I don't have room under my hood for a 2" spacer, so I have only run the 1" and a 1/2" with no noticable difference.
By the way, my vote for your "mostly street" 498 is the 1040 cfm 4150 and a matching 4150 manifold. I just think it will be an all around better carb for a street/strip deal. 80% race and I would do the dominator. My 2 cents.

Wonder if that intake simulates a tapered 2" spacer?

It's something more like this, but for a Dominator. "Super Sucker" style.






R/M Spacer

This is the 2 piece RM spacer we have had good results with as well. It's 1.5" not 2". These things cost almost as much as an intake though! I have seen maybe 10hp over an open 1" spacer. Not worth $150+ to me.

Oh ok,
HVH super sucker style yea the guys around hear swear by them.

Doesnt that intake just look like its a integrated tapered adapter to a Regular 4150 intake?

Kind of like this one

Make your 468-502 BBC launch harder and run faster with Reher-Morrison's Funnel Ram Intake Manifold combination! We start with a Dart standard-flange intake manifold, and then add a 4500 Dominator carb adapter. Then our cylinder head experts port the manifold plenum, adapter and intake runner. Combining the manifold's small plenum and extended runner dividers with the tapered carb adapter produces a venturi effect that dramatically boosts torque and improves throttle response. The Reher-Morrison 'Funnel Ram" gives you instant acceleration, a strong carb signal for precise fuel metering and equal cylinder-to-cylinder fuel distribution. It will make your rat motor roar!

Funnel Ram! ROFL
