I can't answer your questions,
but that combo, if my numbers are right, is gonna come in around 9.7 Scr which is not nearly enough for that cam, even down at sealevel.
Installed at 104*, the Wallace Calculator predicts just 145 psi, with a Dynamic compression ratio of just 7.3.. Under those conditions, if I am right, that 325 cuber, will be a dog until she gets to winding up, beginning around 3500rpm. So then, yur gonna need a pretty high stall convertor for the street, and probably gears around 4.30s, which is gonna make her pretty much a city-only car.
I'm assuming, from your language that the 292 cam is already in the current engine, which means you already know all this.
That cam peaks around 5600, so IDK why you want to spin it to 7000, except for bragging rights. At 6000 she's already going down the backside of the power-curve, and I see no reason to spin her any faster.
I'm not dissing your engine,
rather, I'm trying to warn you to keep the pressure up^^.
Your 318, with alloy heads, and that 292 cam, with a modest convertor and street gears, at sealevel, to not be soft down low (like if yur running a 4-speed), wants Static Compression Ratio of about 11.0, just to take off like a stock 1969- 318; and she really wants 11.5 to be considered hot.
Just so you know, I ran the Mopar version of that cam, in my 367, at 11.3Scr/180psi/ Dcr of 8.75, at my ~900ft elevation. It was not a dog, but it did not like 3.55s, which is all I wanted to run. It did like the 4.30s, but, as my DD, over 95% of the miles I put on her were gonna be hi-way, so it had to go..
Just so you know, I only ran it for one summer; that was all I could take.
Just so you know, in 1999, when I first put my Barracuda on the road, with this cam, I was only 46 years old.
If I had a 318, I'd put a modest solid lifter cam into it, with an Lsa around 106>108 to help get the pressure up, cuz I hate a soft bottom-end. And I'd probably run a manual trans with an overdrive; like a 5-speed.
