Rico,
This is the Intake Manifold and "3 x 2-Barrel" Carburetor' set up off of that 1958 Biscyane 348/315 HP.
The Rochester Carburetors were rated at 225 CFM.
Mark said that the 'port runners' were;
A) Gasket matched
B) Mildly ported
Camshaft was an Iskendarian (Mechanical) - (1960 Stamping)
A) .439 / .439 Lift ~ 317* / 317* Duration ~ 70* Overlap
B) High-Rate Valve Springs
Note; This Camshaft was significantly more 'aggressive' than the 1958 '348/315 HP' stock 'mechanical camshaft'.
Note; Also, somewhere along the line, the 'Cast' {11.00 - 1} Factory Pistons were replaced by a set of TRW Forged
{11.0 - 1} Pistons, and Grant Piston Rings.
