Your thoughts on this cam...
I bought a cam a few days ago (being shipped) and am curious as to how it will perform. The spec.s are
In 204@0.50 Ex 214 @0.50
In 492 lift Ex 518 lift
This will be going in a '68 429 0.040 over w/roller rocker arms, DOVE heads with mild exhaust porting and standard valves, Edelbrock intake w/EBrock 750 cfm carb. This will be bolted to a built C6 with reverse manual valve body (2000+ stall converter) which will be in a '67 F100 2wd SWB. I'm thinking 4.11 gears also. How do you predict this will perform? Tire melter, wheelie popper, regular old street truck (I hope not), ??
The cam isn't really what I wanted but I got a good deal; it came with Cloyes timing set, gaskets and lifters.

thats a mild cam. it will idle like a stock engine but have a bit more power than a stock 460. If you want power and driveability, I would recommend crane's powermax 216/228 #353942 on the mild side or their 226/230 #354551 for a little more rumpity idle. its up to you on how you plan on driving it. But why put it all together and be dissappointed with a way too small cam that you got "for a good deal." In the future you'll probably get the urge to change the cam so you might as well do it right the first time.

Desktop Dyno shows a good bit more power than a stock 460 or 429. I might check into a different cam later on. Yes, 492, 518 lift is mild compared to a lot of others but it should still be fairly powerful.

Depends on what mild porting is. Stock flow on the DOVE exhaust is 135cfm and won't handle anything over about .500 lift. Grinding off the smog bumps and cleaning up the combustion chambers/ports will get you to about 160cfm, good enough with stock valves to use .520-.530 lift with appropriate valve springs (stock won't work well with almost any aftermarket cam that increases the lift). Full porting will bring about 200cfm, enough flow with bigger valves and the right springs to run about any cam you'd want up to around .730 lift. Are you running guideplates and hardened 3/8" pushrods with the roller rockers?
Everything in the valve train/heads is designed to service the cam, so don't waste your time installing a higher-lift, longer duration cam that will sound mean at idle but not be fully supported by the heads and valve train. A well planned engine with a milder cam will outperform it every time.
As an example, the well known CJ had a factory cam with a lift of .506. And those heads had much larger ports and valves than DOVEs, plus guideplates and hardened pushrods.

Yes, it will have guideplates and hardened push rods, as well as new springs. How do you think the engine will perform with the truck I mentioned, George?

Oh yes. Headers and DynoMax or Borla mufflers with chrome tips coming out in front of the back tires.

I for one say the cam is too small. Now before everyone gets bent out of shape, I will freely admit that the most common error of component selection when building an engine is choosing a cam that is too big. However, in this case I think this cam is too small. I can tell you from experience that you will not lose any bottom end grunt with a cam that is even bigger than the one you are choosing. Compund that with the fact that you are talking about using a higher than stock stall conveter and I think you will end up not having the optimum combination. For that engine with a 2000 stall, you should be running a cam with something in the mid to high 220's duration range, maybe even low 230's. If you really want to go with that cam, don't get a high stall converter, your motor will be producing enough torque down low it won't need it, in fact it will probably twist your stock converter to around 2000 to stall. Overall you will still have a good engine if you go with that cam, and I sure won't bust on anyone who gets a good deal on parts, but with that being said, the topic was asking my thoughts on this cam and here they were.

Oh Big Jake, don't make the same mistake I did. 'Headers are not just headers'. 99% of the headers out there are 'cosmetic' and many actually hurt your engine's performance. I have Headman Elites, cermanic coated & believe they are doing more harm than good. They may have cost me as much as 2 mpg. The primary pipes are too large in dia., too short and not of equal length. There is a 10" difference between the longest & shortest. primary pipe.
