I think that is the XE275HL cam? I have one of them sitting on the shelf. What kind of work have your heads had? I’d be pretty happy with that hp number from my nearly identical combination.
Opened them up to 2.05 from 2.02. Block has been bored .30 over. The rotating assembly is pretty well stock. 10.8 compression. It really likes the 96-98 octane fuel. Has good street manors too. I didn’t go with aluminum heads, cause I wanted to keep it as period correct as possible.
