Default BBC 427 roller cam

looking for input for my vette, any suggestions on a roller cam ? Ive talked to Lunati and they suggested the 20110710 but dont think its got enough rpm's 262/270 I .550 E.550 112 split 1400-5400 rpm, I still need enough vacuum for the head light system, no power brakes tho

TIA

Speedy, are your intentions to do a close to stock engine rebuild with a somewhat stock roller profile? The stock cams were pretty tame, and yes you need good vacuum.
Try Bullet Cams see what they say/recommend. I rebuilf my 66 427/390 vette a few years back went with a Crain retro cam flat tappet just because. But JMO maybe keep duration down to the 230-236 range 520ish lift

You may want to post advertised and .050 numbers to be able to compare. What compression ratio are you going to run, what heads, what intake, what exhaust ? automatic, manual, gear ratio ? would all help
