I purchased a very nice condition 318 Poly to put into my 1960 Plymouth Wagon and I was wondering if there would be any value in adding a RV cam to the engine. This is what I'm considering doing to the engine:
-ream the cylinder ridges
-hone the cylinders
-new rings (on original pistons)
-new bearings
-shave cylinder heads 0.030 to 0.040 inches
-port matching intake, heads and exhaust manifolds
-4 barrel intake with 500 cfm carb or 2 barrel 500 cfm carb
-cam shaft

Car is 4200 pounds, I will be using a mid 1990s TorqueFlite overdrive (A518/46RH) transmission with either 3.31 or 3.55 gears

I believe stock cam is 198/198 @0.050" with 0.404" lift and 111 lobe separation. Cam proposed by Camcraft Cams would be a 208/208 @0.050" with 0.429" lift and 110 lobe separation.

Car will not see high RPM use, want low end torque with the ability to cruise economically. Anybody have experience with Camcraft or this cam in particular? Was it worth it? Appreciate the input.

with shaving the heads you may have to also machine the intake to fit.
porting is good for almost any motor.
4bbl carb , i'd recommend a 1901 Street Demon 625cfm Carburetor , fantastic right out of the box
cam you might be satisfied with an rv cam but i'm thinking not! you can get in touch with gary pavlovich at glpavlovich@cox.net for anything pertaining to a
318 poly motor . tell him i sent you ------------------------------------------------later
