I'm putting my stock stroke 440 back together. Years ago it ran a 292/509 Mopar performance cam and lightly ported heads. Ran good I never had a converter or decent trans for that matter. Things came up the car came apart for improvements. I ended up changing to TRW six pack pistons and accumulated a old school ported 906 heads. So long story long I ended up at 11.04:1 measured compression ratio, heads have 2.14/1.81, are not opened enough to need epoxy spots but close. Eddy Torker II intake, mildly ported. 800 Holley DP. My intent was to use a old Mopar Performance 296/.557 cam(used). Upon degreeing in the cam I noticed some pitting on a couple of lobes, I had been on the fence about using this cam, and have always been lucky when it comes to used parts. This one has me concerned. Rocker arms are Isky iron adjustable. I would like to stay somewhere around the Mopar .557 cam range, maybe bring the rpm range down a bit, no need to sling those big heavy TRW/speed pro slugs above 7k.
Don't want to cause feuding, and I'm not stroking it changing the heads to aluminum, so don't ask. This engine is staying the way it is till I wear it out or window the block. Just looking to see what other people's thoughts on which way I should go with a cam in that area (modern profile to improve on Mopar Performance cam). Converter is around 3800 rpm with a less powerful engine, rear gear is 4.10 with 28" tires, car weighs ~3400# with my fat *** in it, I'm hoping anyway.
