:iagree: Not puttin' you down dude ...just trying to help. You'll find that the cam won't have any power until about 3500-4000 Rpm. That makes for lousey street driving. I built a 396 when I was 19, Put in a big cam; It wouldn't pull a hat off your head until it hit 4500. From 45-6000 it was strong, and the idle sounded cool, but I could have been beaten by a 6-Cyl on the street.Just my $.02

Hey AsRoff,
OF COURSE we're still friends! At least I HOPE so.
No problemo.
I was just trying to encourage him to use the 'better' of the two devices.
The only time I'd consider a carb. is if the rule book didn't allow FI.
In the next three to five years carbs will be just about faded from the scene.
If one is going to learn how something works it may as well be the 'newer' technology.
Granted the FI is also pretty old tech. but the basic design hasn't changed in a number of years.
I dont' remember when carbs were 'invented' but they also haven't changed much since then. Was it back in early 1900s on the Ford Model T?
Those carburetors are ANCIENT technology. :yesnod:

You have emissions testing!?! I do not think there is any way you can pass a sniffer test or a roler test with that cam AND a carb. Visual inspection only you could, but if they do anything more then it aint gettin' a sticker without some money slid under the table. FYI, anywhere from $50-100 is customary on top of the cost of the inspection.

tworottiedogs, I just thought about this, how do you pass emissions every year, and where do you get your vette inspected?

Re: Setup, Estimated Horsepower? (tworottiedogs)
Well it all depends on whose there inspecting cars that day, some guys are normal people, they don't give a crap about the enviromentalists. But some people are ******, they've got to check every little thing, a few years ago my dads '69Chevelle wouldn't get passed because it didn't have a cat. There's one place around here though that I'd e afraid to take a new car, they do everything, put you on the machine, look under your hood, and it takes about an hour to get tested when your the only one there. Anyway, if I have any problems then I'll drive to New Bern tworottiedogs. Talk to you later.

Too much cam on a regularly driven car. You will probably need a higher stall converter and you may have difficulty with your vacuum assisted stuff (like brake booster). I think you will be dissapointed with this cam. Most people need to select the cam they think they want, and then back down some. Most everyone wants too much cam. About 220 @ .050 is enough on the intake and maybe a little more on the exhaust.

I don't think carbs are going anywhere. Holley, Edelbrock, and Barry Grant have all recently put out new designs or variations. They wouldn't all be investing this money if carbs were going away. Carbureted WOT performance is almost identical to EFI and they're much, much cheaper. A carb intake & 4bbl cost about $400 new. A Super Ram and a FAST programmable EFI system plus bigger fuel injectors are going to be about $2500 new. While it's true that we're not going to see carbs on new production cars any time soon, there are millions of vehicles still on the road that use carbs. If you're in a state with no emissions requirements and you're low on cash it's definitely the cheap way out. If there wasn't a price difference of several grand it would be a no brainer - EFI every time.
DrPepperKid: A 234*/244* cam is going to need about a 3000 rpm stall converter. I once ran a 236/236 cam in 350 and it bogged big time off the starting line with an 11" 2200-2600 rpm stall converter. It needed a 10" 2800-3200 rpm stall converter and so will this cam. Also I think you meant #041 factory cyl head castings. These aren't going to work well with the big cam either unless they're ported pretty good. Just my $.02.

Re: Setup, Estimated Horsepower? (CFI-EFI)
Well guys, with all your remarks I decided on a different cam, I've began looking at the comp cams and the 270H seems pretty close to what all you guys have been saying. Its int.224, exh.224 duration, and int.470,exh.470 lift. I think its the way to go. Now regardless of what you say about cats only being required on '74 and up cars, well don't think i'm lying because I'm not, the guy wouldn't pass the chevelle without a cat. so my dad put one on it, but since then my dad has sold it, so it doesn't matter anymore. Talk to you later.
