I am building a budget BBC with parts I have. Here is what I have so far. 454 bored 30 over with speed pro 340 domes pistons. Stock crank. Merlin World Grumpy Jenkins 119CC iron 320 runner rec port heads with 2.30-1.88 valves. Piston catalog states I should have right at 10.5 CR. Weiand Team G dual plane rec port intake. Engine is going in a 1955 Chevy Truck, auto trans with 3000 stall, Ford 9" with 4.11 gearing. I am not going to be racing this truck on the street or track. I want a cruiser with radical idle and low end power. I am going with the hyd roller cam. I am looking at the Lunati Voodoo #60213 Hyd roller. 241/249 625lift on 110/106. or the Lunati bootlegger 240/252 595lift on 108/104. What differences am I looking at between these two cams. Pros and cons of each.
