pump gas 454 combos?

[68c10owner]

I`m still searching for a 73-75 c-10 to make into a street/strip hot rod but I`m interested in hearing what kind of engine set ups you guys are running to push these heavy trucks to the low 12`s-high 11`s. Not going to cage it so can`t go faster than 11.49 and must run on junk California 91 pump gas. I`m planning to do a flat top 454 with closed chamber ovals. Compression should be around 9.5:1. Heads are at the machine shop now and are 390 casting closed chamber ovals that are listed at 96cc chambers. They are getting 2.19/1.88 valves and just some mild porting. Plan to keep the rpm range at no more than around 6200rpms. So what are you guys running?
