I have a good used Bullit solid roller cam in perfect shape. All lobes like new , dist. gear perfect.
Here are the specs from the cam card
Cam part # 506000
Duration at .050 intake 266 exhaust 274
Lobe lift intake .4150 exhaust .4190
Lobe seperation 108
seat duration at .020 intake 299 exhaust 308
gross valve lift intake .664 exhaust .670
valve lash intake .022 exhaust .023
This is a very strong cam from 3000- 8000 rpms
Made 615 HP with 408 ci and AFR 205 heads 10.5 CR
This cam with open headers is loud. Always wins loudest car at track award.
This cam needs race gas for the track.( OK with pump gas on street if not raced)
I paid $300 and will sell for $100+ shipping and if you are not happy with the way the cam looks I will refund your money if sent back immediately.
