shannont Jan 25th, 04, 10:54 AM Time to decide on a cam...... 540" 8.5:1 with F3R Procharger.... Any ideas would be great, because I'm lost here. www.teamprickracing.com/f3sc (http://www.teamprickracing.com/f3sc) Thanks, Shannon Bomber '67 Jan 25th, 04, 1:16 PM Shannon, I'm not sure how you can get to a 540 with an F3R and be lost.... What are your current power goals and planned useage of the car - usual stuff like drag only, king of the street, etc. If you have no plans on spinning the engine past ~ 6,000 rpm you can probably get everything you need out of a regular hydraulic flat tappet (I just have a baseline blower hyd FT in my SC 468, .547 lift 232/237 duration 114 center installed at 112). With 540 cubes you can easily go several steps larger and still have a nicely mannered engine. If you go roller, with the F3R you can easily go upper .6xx's lift and ~ 250/260 duation and still have a happy street engine. What heads do you have and how well do they flow? If a street car then your total exhaust system will need some thought, especially as you go bigger on the camshaft. Thomas shannont Jan 25th, 04, 1:22 PM Thanks Thomas.... The heads are Pro 1 345's (untouched) The car will see very limited street time so the cam can be pretty risky. I want to go with a solid roller setup. I plan to shift in the 6500 range so I can get some rpms out of my blower. With my current pulleys it will only be turning 44k @ 7000 rpms. Shannon LYK2ROC Jan 25th, 04, 1:46 PM How about this one: Comp Cams solid roller 11-694-8 adv duration 300/308 duration at .050" 255/262 .652/.652" lift 114 lobe sep 3500-7000 rpm Doug Herbert also makes very inexpensive, billet, solid roller cams for around 209.00 Give them a call at 1-800-444-7373 and ask them for a recommendation. They grind their own cams. They go from .569"-.712" lift so there are very many to choose from. Good luck! :cool: | ||
