You wanted Whiplash cams for Magnum engines and now we’ve got ‘em! These hydraulic roller cams are designed to work in carbureted, non computer controlled engines.These cams are designed to work with low compression engines only. Stock Magnum engines usually have to much cylinder pressure to use this cam. If you are running stock Magnum compression you should consider one of our cams that is ground on a 110º or 114º LSA. Call us with any questions or concerns before ordering.
Like all of our Whiplash cams these rollers will have very aggressive idle characteristics and accelerate very hard right off the line, no waiting for the RPM to come up. These are new cams, not regrinds and you can use the stock oil pump drive gear. These cams will require our 1110 valve springs and our 1278 retainers. We have a tool, #66784M that will allow you to change valve springs with the heads on the engine. We will sell or rent this tool.
Available for 5.2 and 5.9 engines.
These cams will not produce as much vacuum as the stock cams. At an idle you may need to put both feet on the brake pedal. When driving the vacuum will come up. To increase vacuum you can add an electric vacuum pump or a vacuum reserve canister.

I personally would widen the lobe centers myself. For better help,you might add what trans(stick/auto) converter stall(?), rear tire size & rear end gear ratio. You could also call Oregon Cam grinders,who can do a similar grind,a lot cheaper. You will most likely need a custom length pushrod set ( aftermarket cams,usually smaller base circle ground. Hopefully this helps. Do lots of research, ask lots of question s,before you order a single part. Saves money ,in the long run.
