i'm building a 327 for my 68 chevelle and i'm looking for a cam to put in there but i'm stuck, i want a cam to do daily driving and to race at a trackon friday nights or on the streets.
I did find a cam and its the Comp cam Extreme Energy 4x4 cam but the thing is it says its more of a off road cam but when i do dyno test i get alot of torque of the line, around 345 i think and right after it peaks to 395-400 for torque and starts to go down the Horse power reaches 400hp.
Have any of you heard of somone putting a cam like this in a engine for a muscle car? i have tested others but don't do as good as this one.

We'll need more info... Other specs... compression ratio, pistons used, power adder(if any), head specs, induction, etc... Can't offer much help by simply guessing what cam might work.
"R/V" cams are very common, however.

pistons= K/B DOME PISTONS
compression 10:1 or 10.5:1
1.94 1.50 double hump heads
stock rods
stock crank (not cast)
tranny= turbo 350 with shift kit
what else you need to know?

Heads stock or ported?
What size carb and which intake?
Flat tappet, solid roller, hydraulic preference?

Don't use more than a 650 carb, for your engines sake. A 327 in all honesty, just doen't need more and there's something to be said about running lean or rich, but suffice to say, a 650 will be plenty. I've seen cars run 10's with merely a 600cfm, btw.
What size are the chambers here, about 64cc? Well anyway, for a good street engine with manners, but still able to make power, you can probably get away with a decent cam. The 327 is a very good one and you can make like it's a 350 for the most part in building one.
My 1st thought for this package would be the Edelbrock cam that's commonly sold with the Torker II intake. Part# EDL-5002
Specs: Lift- .488 (int/exh) Duration @.050- 232int. 234exh. Cost is about $160 and includes lifters and installation lube.
From there, I'd consider some slightly smaller as well, within 10* duration, or larger (but not much), keeping the lift under .530 and duration no more than 242/254, keeping in mind, that's A BUNCH of duration for that small a motor.. Or you could get crazy and use a TFS-31402002... But I wouldn't do that.. heh
I actually think any of the 3 TFS offerings would do well or better.. However, those 3 cams are recommended for TFS heads, which have better flow and velocity characteristics than stock style iron heads. The TFS-31402000 is probably the most common TFS cam sold for engines like this, but I'd be lookin at the one listed in the middle, the TFS-31402001 (230/234@.050 and .528/.539 lift), but those cams are not really cheap($250ea.). Those numbers are from the Summit catalog.
