Is This Cam Streetable?
I plan on building a stock stroke 360 for a 4-speed Duster, 10.5:1 - 10.75:1 compression ratio, good internals, ported Eddies or Procomps, etc. The cam i'm leaning towards is one of Lunati's Voodoo "retro-fit" hydraulic rollers. Specs are as follows:
Advertised Duration (Int/Exh): 294/302
Duration @ .050 (Int/Exh): 243/251
Gross Valve Lift (Int/Exh): .560/.565
LSA/ICL: 110/106
RPM Range: 2600-6600
Is this reasonable? I'm not familiar with driving a carbureted engine of this caliber on public roads to be honest. Car should be fairly light, no a/c no power steering no power brakes a833 and some decent gear. Not sure on the ratio but it feels like 3.55's+. But I was going to ask before I got ballsy and ordered it and ended up with an engine that's way too temperamental or something.
Anybody here running a cam like this on the street a lot? How does it do
Everybody loves a big cam; but ask yourself why you want such a monster.
With 3.55s and 27 inch tires, you are gonna want a lot of TC to make it work. Then consider that 6600rpm will get you 61 Mph
EDIT in 2.45 low.Then consider that the power doesn't start until about 5000(45mph)
edit, still in low.Is that what you want? A car that is killer from 45 to 61? And it will most likely blow thru the tires the entire way?
I binderdundat. It mostly sucked....This cam will suck your Dcr down to 7.86ish, Which is about stock 360 territory. Granted your cylinder pressure might be 155 ish. What this means is that at low rpm settings,she will feel like a good 360, and that's all. So on your way to 45 mph, you will need that big TC,or more gear, just to stay ahead of the stock boys.

I hate to go and tell a guy what he needs but your combo is almost exactly like mine;it's scary.So I'll offer my experience instead. And I 'm on my 3rd cam, trying to figure out what is street fun.
-Cam #1 was a 292/292/108-.549(1.6arms)....Too much for me. It ran gangbusters from 5500 to 7000. That is way into speeding territory with 3.55s and 27s.
-Next I installed a 270/276/110-.538/.549 cam. This cam was everything I had hoped for.Gobs of torque right off idle, enough power to go 12.9/106, and with a 600VS, I could lean it out to get 32mpgUS. That was a sweet cam
-Next I installed a 276/286/110--.549/.571 cam. One might think such a small change in cams wouldn't amount to much. One would be wrong.I lost some first gear torque, which I got back by going to a 3.09 first gear(up from 2.66). I gained a top end rush. And a much fatter midrange. I lost the ability for gas mileage. This combo will blow thru new295s in 2nd at any speed up to 50mph by just standing on it. If they are already spinning, as in the car is accelerating, they will never stop till I shift at 82mph(I also have 3.55s)
So now it is continuous fun from the first stomp to at least 82mph.
The 276 cam brought my Dcr up to 8.6, and the cylinder pressure up to near175psi. I am very pleased with this, and will run it this way for as long as it hangs together. It runs 93 in the 1/8 with no tuning at all. It has been giving me giggles since 2004 like this, 100,000 miles or more. Oh and FWIF; it has always burned 87E10 from day 1.
The 276 cam I got from Hughes. It was an HE3037AL- .050 specs of 230*/237*
