Ah, I was referring more to valve/piston clearance when shaving the head, but that is still good to know. Yep, shooting for 7800-8k occasionally if it makes any power there.The 252/256 duration 10.0 and 10.8 lift Tomeis didn't require any clearancing. As far as their power band goes.. they had a small tq dip at 3500 but a large HP spike 3500-4000 that stays on boil up to 7500 and then remained flat to 8000rpm. I'd say you better plan to rev the dog **** out of those 272's to make 'em worthwhile.
hello! many thanks to adam777. In other, more boring news, I replaced the clutch master cylinder as well yesterday. Pretty painless.
