Yes the cam should work wonderfully with IR induction due to the low overlap. Low overlap means less reversion, better drivability in all weather conditions and at all altitudes. More stable carburetor calibration. The exhaust valve opens early enough to make the cam forgiving about exhaust system back pressure.Web

DESIGN OF THE MASTER CAM The Master Cam is a solid piece of tool steel. It's outside radii reflects the final shape of the cam lobe. This is the master that controls the shape of the camshaft as it is ground by the grinding wheel. The exact lobe design is the result of computer plotting, sample grind-ing, dyno tests, and actual "on the road" usage.Web

This page discusses poly 318 and other A-block camshaft profiles, regrinding, and lifters. While the 1957 – 1958 "Dual Fury V-800" poly 318 boasted the hottest factory bump-stick, it was still terribly undersized for what the engine can make use of with factory spec equipment and certainly for high-performance builds.Web

There are no easy answers to complex problems. The CB47 cam is a copy of the AR factory Group1 cam of early 1970. It has 11mm lift, 246* at .050" and is an excellent cam for the 1750 and 2000. Use with 0,45mm intake and 0,48mm exhaust clearances, for 290* and 284*respectively. They work well when set at 43-67-64-40.Web

I've found that it's usually a task best left to the cam grinder to make. I'm not going to get into cam selection in this article, but I should talk a bit about the effects that duration has on an engine. LSA for a performance ground cam is typically between 106-114 degrees. Sometimes even less than 106 is ground for stroker engines.Web

Another graph of camshaft lift vs. crankshaft rotation. In this image, I'm showing two different exhaust cam profiles.
