318 power?

Sounds like that engine will be a real screamer. Your engine specs remind me of a engine I had built in the early 80's and put in my E body.
30 over 340, standard 10.5:1 compression, standard 340 crank cut 10 under on rods and mains, balanced lower end rotating assembly, custom machined large valve heads, spring and valve guides stems cut to allow plenty of compression due to the high lift cam. The cam was a hydraulic flat tappet and had a 512 intake and 525 exhaust. I had to find the adjustable rockers, spacer springs and push rods from a earlier 273 hp engine to get the proper valve adjustment. I had a MSD and factory electronic distributor, fuel was fed through a 6 pack set up with all carbs set up with mechanical accelerator pumps and power valve metering blocks with mechanical progressive linkage.
That engine screamed up to 7300 rpm's and was well mannered as a daily driver. The car was a blast to drive, good luck with your build.
