3 engines, 3 intakes

Engines:
416 (340, .030 over, 4” stoke) eddy heads w/minor bowl work & gasket matched, 10.5:1, Howards solid 254/260 @ .050 .550/.555 on 108.

340 .020 over, iron heads 2.02/1.60 valves gasket matched, 10.4:1 mp 296/557 solid cam, hooker 1 3/4 super comps. Auto w/4.30 gear In 73 challenger street/strip, mostly strip.

stock ‘77 360 currently stock cast iron intake w/adapter and eddy 650, w/68 340 exhaust manifolds thru 2 1/2 exhaust in 67 Cuda street only 4 speed w/3.23 sg

Intakes:
M1 single plane, this one’s been cut to fit the 416 so I guess this one stays.

Six pack currently on the 340 but I’m thinking it might be better suited to the 360 for street duty

Rpm air gap on the shelf but I’m thinking this one for the 340 with 750dp. Better top end and easier tuning for strip car.
What’s your guy’s thoughts?
