Cam Suggestion
« on: December 16, 2008, 10:52:42 pm »
I just had a new 350 built for my truck.  The valve springs can handle .450 inches of lift.  I was told to go with a 220 duration cam with not too much more than .450 lift.  I'd like to get that choppy idle sound but I don't want to sacrifice low end power.  Any suggestions?

More details on the application. What's it going in, transmission, tire size, exhaust, intake, intended useage?

if your just looking for the "choppy sound", get one of those crane thumper cams. You pretty much get the sound without having to run a big stall and stuff. Here's a link for you to hear.

1974 chevy c10, turbo 350, tire size will change but they're a goofy size.  its like 30 by something....I have to go check the side wall.  They're good sized tires.  30 something x 10 by 15 Headers, Wieand Single plane manifold...I just want a nice running street truck that will take a visit to the drag strip.

Why did you chose a single plane intake manifold?

You can modify a single plane with a divider to improve booster signal.  But it won't have the same low end response as a 180* dual plane.

That's ok, I can always change the intake, but it's all I have right now and money is tight.  I have $200 for a cam and lifters and that's it.

Well regardless of the size you pick, Summit offers cam/lifter kits for about $90.  And I'll bet Vile's gonna recommend a cam from them too, as he often does.

So that leaves enough money to sell the Weiand and pick up a nice used dual plane on eBay or Craigslist.  Of course, this is assuming that you won't need the rest of that money to replace valvesprings, seals, etc.

Everything on the engine is new.  I haven't had the cam installed yet but it has rebuilt heads.  Valves, Valve springs etc...The springs can handle .450 lift so I want a cam that can do around that.  I will not run any summit part in my engine.  I'd rather spend the extra money for a Comp Cams.  I should also point out I'm looking for a hydraulic cam.  I'm probably not going to replace that intake but I'll check craigslist.

Intriguing statement since you live so close to Summit Racing. What happened? Did you get some bad parts?

Well if you are hung up on brand names the ISKY Mega 264 comes to mind.  It won't have a choppy idle, though.  And I wouldn't run it with less than 8.5:1 CR (9:1 would be better).  But my advice is based on my comprehension of David Vizard books and magazine articles, not hands on experience, so keep that in mind.

Summit racing has terrible customer service and I've heard many horror stories of their name brand parts ruining good engines.  I would much rather stick with a name I trust.  The engine should have a 10 to 1 compression ratio.  I'm looking for the lopey idle, but I don't want it to the point where I'll loose a lot of my low end power.

Well with 10:1 you could go a bit larger without loosing much low-end.  Maybe an Isky Mega 270 or Comp Magnum 270, but these cams have .465" and .470" lift, respectively.  Are your lift restrictions based on spring pressure or coil bind?
