Sounds like you are going to have a real hot rod on your hands. Just curious, what is a stage 1 cam? What does that compare to and who is the manufacturer of this cam?

A stage 1 cam basicly kicks in at around 4K rpm, and really takes the car up to a good rate of speed, the dif between that and the orig RV1 cam is that the RV1 cam got me off the line quicker and dies out at around 4K rpm, then it just acted like a stock cam. Buy what makes the stage 1 work is that it has a few extra lobes on it, and it provides more lift, and duration. How ever since it kicks in so late, the flat top pistons will provide what I need to get off the line quick. THe reason why their tops are flat is so that they can push down the fire quicker, providing me the torque I need to get a good time off the line.

You got a serious driving machine when your ready to go aout and have fun. Good Luck and don't drive to fast. If you do just outrun the cops.

COOL VETTE MAN!!!!!

okay.. all cams for a given engine have the same number of lobes. there is one lobe per vavle.

what about the cam kicks in around 4000 rpm?? if thats where your torque starts youll be sorely disappointed.

the flat top pistons arent flat to push fire down
quicker. in fact the pistons dont push during the power stroke, they are pushed. they only push during the compression and exhaust strokes.

they are flat to give you a higher compression ratio.

higher compression will generally give you more torque.

why dont you find complete specs for this cam... ill even run a desktop dyno simulation for it and post the result. I think you may wind up being sorely dissappointed if you build a high horsepower engine and try to compensate for the lousy torque curve this gives you by increasing compression slightly.

you may be able to beat anyone if you start racing them at 60 mph but fall flat and look silly from the line.

let me give you an example

here are the candidates

350/300,350/350,350/370

all three produced 380 lbs of torque

the 350/300 reached its peak torque at a very modest rpm
this was the best off the line of the three.

the 350/350 got its peak torque later but still respectable.

the 350/370 got its peak torque very late and was the least peppy of the three off the line.

out on the highway the 350/300 was the weakest of the 3 while the 350/370 was the strongest.

what are you trying to do with this car... run a road race or beat ricers at the stop light?

Like I said guys I am not trying to go out and race people. However there are more fators that We are tning with the engine that will amke it go faster. THe guy who is rebuiling it is suspecting it to be like 330HP+ and it is a 350CID Chevy SB. He took a CADDILAC NORTHSTAR (FUEL INJECTORS 165HP) and turned it into a carb fuel fed (custom casted intake he made) and makes it push out 400HP, go figure. I highly doubt this guy is going to dissapoint me... I am not trying to sound like that stupid IROC loser on that radio show, however I think you guys are seriously under estimating wht this guy has up his sleeve. My dad asked if it could keep up witht he foriegn racers, and he laughed for 5 minutes... and said when I get done with it you wont know what happened.....

my offer still stands on the computer simulation..

ill post it here and then you can hear quite a few opinions.

a one eyed man is king among blind men

by the way.. what is your gear ratio??

remember there is a HUGE difference between FAST and QUICK!!!

|UPDATED|10/30/2004 12:57:53 AM (AZT)|/UPDATED|

Put your vette up on jack stands and rotate your wheel around once and count how many times your drive shaft rotated, that is your rear diff's ratio. I suspect you got a 3.08 like what I had. When I did my engine build I put a comp cams 270 magnum cam in it. The specs are .470 lift intake/exaust 224 duration@ .050" at 110 lobe sep angle. This cam is rated to start its power band at 1800 to 5800 rpm. Ben is correct to say you might have a screaming motor on the top end but it will fall on its face on the low speed launch. I was disapointed with the launch on mine so I swapped to 3.55 gears and it made the car alot more fun to drive. I love the cam now cause it starts to make good power right were the gears allow it to start. If your power band is high, you might need a 3.70 gear and a higher stall converter since you still are using your th-350 trans. I am using a 700r4 trans so I can have a slightly lower ratio.

Does your engine builder know what you got for a drive train? He should know what you need if you tell him your trans and diff ratio.

He asked, and I told him the orig turbo hydrolic 3SPD 350, believe me I was not quite sure if he was correct at that point, but if you see what this guy does with stock blacks, and other stock cars... He is builind up another 77 Vette but with a Stage 2 cam. He is really good, and he builds racing engines, and is very well known in Vegas, and some parts of cali, and utah for it. People come into his shop from all over to get their engines done, he expects my car to do "Well over 150MPH" And have a good launch speed, and continue with only a slight dropage. I mean I don't know if u guys know what an RV1 cam is? An RV1 cam is basicly for a big truck pulling some serious weight, or a Motorhome, where they need some good torque coming off from the start... I'm getting a stage 1

Yes, but truck's usually have high ratio gears in the diff. Like 3.70 up to 4.55 and higher. I'll think though by saying "stage one" means mild street cam. So I think you should do ok then if that's the case. You still might want to look into a higher ratio diff gear for increased fun factor. Just dont go too crazy.
