I’d do something high 250’s low 260’s @ .050 on a 110. Get it up over .600 lift (.630-.650 range) to turn the heads on. Something tight lash with a street lobe. It’s got a 4.10 gear. Work fine long as he saves the overdrive for e-way use. It’s gonna have an Indy single plane and M/W heads anyway so it’s not like it an off idle engine. And I’d probably top it with a 1050/4150 annular carb. A 1.56 Venturi 850 would also work well.
