Looking for a healthy street cam (4v-351c)


Recommended Posts

When I got my '73 Mach-1, it had (and still has) too big of a cam. I am looking to simply looking for a healthy street cam for a daily driver. I like a little lope but not looking for a choppy idle. Unfortunately I don't have the cam specs. When I look at the paperwork, it just says it had an: "Isky cam- radical idle"

  My car has 3.50 gears, a c6 auto Edelbrock Air Gap intake and a 750cfm (vac 2nd). Again, I just want a healthy sounding car that makes enough power to get out of its own way that I can just "get In and go". Due to funds available, off the shelf would be ideal. I would also prefer a 112' LSA.. 

thanks..

Try this. There I a spreadsheet one of our members put together to get a starting point.

Also, if you call Comp Cams and speak to a tech they are quite helpful with cam selection whether you are looking for a custom grind or off the shelf.

I love my comp 280 magnum, my car screams when you hit the loud pedal. It has a noticeable idle but has no problem running in gear at a stop light.

Wow I was tying to look at the Isky sit to see if I could determine what cam you have but their search function is terrible. And wow, they are pricey.

Yeah, their site isn't very good. And yes, very pricy.

Do you have flat tappets or roller lifters, hydraulic or not?

 

My cam is a little healthier than the off-the-shelf Magnum 280.  It's a Comp Cams Magnum Retrofit kit (K32-421-8) - hydraulic roller cam.  Specs are 274/274, .566", 214/214 @ .050".  Not sure what your budget is, but this kit covers everything except for roller rockers.  The intake valley would require 2 holes drilled and tapped to install the lifter keeper 'spider' as well.  CompCams says expect around 400-ish horsepower when matched up with some other performance goodies targeting that range of performance (intake, carb, ignition, headers, etc.).

 

If you're looking at a flat tappet replacement cam, you'll still want to go with new lifters and pushrods, since the current lifters and rods are broken in to the current cam you're wanting to replace.

 

I'm sure the Magnum 280 will put a smile on your face, though. ;)

Thanks everyone.. I found this one from Crane (H-278-2) that caught my eye. Any opinions?

222/232 @ .050"/ .539/.534 - 114'

 

Thanks..

That cam will work but if your 73 351C is stock (low compression) I would not go that big. The old 204/214 or 214/224 Motorsports grinds work well even with the stock valve train parts.  I ran the 214/224 cam in a mostly stock 351C and it ran good even with the 2.73 peg leg.

73 conv. 460, D0VE large valve heads, Performer RPM manifold, Voodoo 227/233 cam, Holley 950 HP carb, C6 trans, 3.25 trak-loc.

I have 10:1, 4v heads, and 3.50 gears..
