Low Profile Single Plane Intakes

Wow, lot's of experience coming through! I appreciate all the thoughts and advice. I'm wondering now if the Dual Port on my shelf might be interesting in combo with the 308 heads on a 4" crank. I suspect it won't want to rev high but the throttle response and torque might be crazy. In the light Valiant with tall gears that should be interesting. Definitely the other end of the spectrum from a genuine 273 Commando.

Like I said at the start, I'm departing from my approach since the 70's of running traditional racer modded smallblocks. Something interesting but mild sounding in a mellow looking street car suits my more relaxed old age, but I can't resist packing a big stick while walking softly.

Thanks everybody!
