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!
