You have three options as I see it.
1: Built the stroker 393W, max CR 10:1, and leave it alone. No hair drier.
2: Add hair drier, max CR 8.5:1. Have piston tops and combustion chambers ceramic coated for added insurance.
3: The 429CJ was an option on '69 Mustangs. Todays 460 is a stroker 429. Get a 460, modify it to your liking, and bolt it in. This could be your most cost effective route. Plugs and
oil for maintenance, and better resale value.
