Low Profile Single Plane Intakes

So here's probably an uncommon request. I'm looking for legit experience with low profile single plane intakes on hot smallblocks. Why? I'm playing with the concept of how far I can push "273 Commando at a glance" subterfuge. I'm not a racer anymore but want to pop the hood of my 66 Valiant V100 and relate the look to the Commando label.

I'm using a 1990 roller cam LA block and have both a pair of worked 308 heads with 2.02 intakes and a set of Indy 360-1 aluminum heads. On the exhaust side I have 68-70 hipo 340 manifolds that I figure to apply the highest flow single exhaust possible. Still haven't finalized quench piston 360 or flat-top 408. The intake needs to look as much like a flat single plane 273 4bbl as possible. I include consideration of a stock intake, Extrude Honed with 4-hole plenum milled open, and any aluminum aftermarket shape that looks similar. I even have an Offy dual-port single-plane and a Holly Streetmaster on the shelf. This is all about a sub-2800# Valiant using a low first gear 904, 2.76 gears and as much motor as I can make look like a 273 Commando. Street driver with an unlikely looking old man behind the wheel...

I appreciate any input from anyone who's actually worked with low profile single planes across race/street/displacement variations.
I get that many have theories and opinions, as I do. I'm really looking for hard data from folks who applied real parts on real motors in real cars.

Thanks!
