Re: Need some cam info
I make a REALLY good living fixing ink stained peoples' vehicles.
They all make the same five mistakes,
1. Believe ANYTHING they read in magazines.
2. Buy too big of carburetors.
3. Buy too big of Cams.
4. Buy too big of headers.
5. Listen to anyone at a 'speed' shop.
1. Out of the many magazines our little bunch has been in, we never once told the truth. Nobody does. That's why they are called entertainment. No one wants to hear that most of every 'Cool' street machine is 99.5% (or more) factory parts. That is especially true if the ride is streetable. Besides, magazines make their livings selling this stuff... think about that.
2. Listen to Holley, not the speed shop. They tell the truth 99% of the time.
That huge open plenum, single plane intake manifold isn't doing you any good either. (It sure looks cool...)
3. Cams. High lift, long duration, and big overlap may sound great, but you will pay. No vacuum to work that giant carb (not to mention power brakes, vacuum advance, ect.), no idle, no power in the normal operating range of your vehicle, and to make any power, you have to rev right to the edge of destruction (or beyond) of your otherwise stock parts... (and you thought it was expensive before...)
4. Big headers compound all of the carb, intake and cam problems, and make the custom exhaust shop guy smile.
5. 'Speed' shops are there to sell parts, and clerks are not experts in anything but sales.
If they don't have at least 500 hours on a dyno, they are hacks & will say anything to get the sale. They should be flipping burgers at the local burger doodle.
If anyone can't verify the results of their claims with a dyno pass, tell them to get lost.
Call Vic Edelbrock, tell them what you want to use the vehicle for, and see if they make a matched carb-intake-cam & lifter set, and take their recommendation on header tube size and design.
Happy Jeepin' Folks. Aaron.
