Without looking up the card the engine machine shop gave me here is what I have:

1973 400 with 440Source 499 (4.15") stroker kit - block decked .010"
flat pistons, 4.375" bore (35 over)
Eddy RPM aluminum heads 88cc chambers
Fel Pro .055" head gaskets
Comp cams 21-223-4
Base timing is 16*, total is 34*

According to the calculator, my dynamic compression ratio is 8.51:1.

I need to increase the ABDC number to get my DCR down a bit.

Would this be a cam "the range" that would get me down where I need to be for pump premium but also leave me a docile motor that pulls enough vacuum to operate the HVAC box and power brakes consistently?

Or something like this:

Using my very limited cam knowledge this computes to a ABDC value of 66 (Comp Cam) which drops my DCR to 8.13:1 which might give me a better margin with the pump gas? However would this be too much cam for my needs and drivetrain? I am not necessarily going to go for this exact cam but something close to these specs...

So no opinions on the cam's I threw out there? I see Lunati has roller cam/lifter sets for around $750 which is pretty dern cheap. Are these any good for a street (no more than 5500-6000RPMs) motor?

The super fat head gaskets are like $300 bucks a set. I think I'd rather save the $$ towards the new cam/rollers tbh. I know I can get the motor to run on 93 pump gas without having to sacrifice timing or compression.
