I do the Bolt in #5 too

Nice build, a set of Shady Dell stage 2 Eddies would work Perfectly with that cam, Mine is 266/269 @.050 but similar .585/570 Lift. With a roller cam they would probably net you close to +50hp with no downside. Not sure if the OOTB RPM intake would flow quite enough up high on that big a motor without some work though (I run a ported Vic 340), but your peak power would probably raise another 400-500RPM.

BTW...I'm also running a way too small 1 5/8" x 3" header but that's because I'm not sure a 1 7/8" x 3 1/2 (the size I run on my 427" SBF) would fit the chassis, bang for the buck the cheapies do just fine
