procharger or heads & cam alright guys procharger or heads & cam. first i didnt want to do a procharger because i was scared that a freak accident would happen and my c5 would run like sh*t and blow up, i am somewhat over that fear now. but nothin beats the sound of a cammed out car especially when it comes from a c5, but on the other hand a procharger under the hood would sound just as damn sweet. what do you guys think? now i was also wondering whats the difference between a p1sc head unit off a c5, f-body, or lets say a 99 mustang gt? are they the same head unit? i understand that they mount differently but could i just by one of these 3 head units and get a c5 bracket??? would it fit? if it would fit i was just going to get intercooler piping and a intercooler of choice...i dont want to affect my gas mileage all that much and i understand that heads and cam would prolly drop 20mpg in town to i dont even want to know, give me some ideas on building a procharger kit or just doing heads/cam. im stuck, one day i want to do H/C the other procharger...dammit...help me out guys
You could do the ProCharger and a camshaft, that way you have the sound and the power. Our blower camshaft will give you a great sound and will give you added power. The blower head unit is turned around on the C5 engine, to run off the accessory belt. Give me a call at 260 244-4808 for a great price on the C5 ProCharger kit. The price is much cheaper over the phone, as ATI has pricing guidelines. Bob
I was in the same dilema about a month ago and i chose the heads cam route for longevity and reliabilty and plus is didn't want to have to deal with the freak accidents as you described above.... i went through so much trouble with my blown cobra.....

I would go with a head and cam car. No belts to worry about and you wont have to run race gas to turn up the wick. Here is a video of a friends car. Mods are in vid and he is still getting mid 20 mpg on freeway. Car really screams up top too...

20 mpg on freeway? grrr i get over 30...thats a pretty huge drop, the in town mpg is prolly hellish huh. that you guys for the replys! i still dont know what i want to do...i need more info come on guys!!!

I have gone back and forth over this same decision and still do. Right now I am running a 100 shot and I think my next move will be a forged motor and more N20. I have one friend with twin turbos and one with a supercharger, they both have issues from time to time. Nothing big but if your the type that dosen't work on your car that could get anoying.
With a nice head cam package and a small shot of nitrous I think you would be very happy.

I both set up are great. Its all going to come down to what kind of power you want. The P/C will have a little bit of lag until you get into the higher RPM's where as the an N/A set up will give you that instant "hit" so to speak. I'm in the same boat as you.
I'm looking at a D1SC set up or a 402 set up. I'm leaning more towards the the 402. I'm only looking for about 500rwhp so the 402 seem to be the best package for me. I'm not really into the track so it's just better for me to go N/A. N/A always seems to be a little less of a pain when the weather changes.

Are you going to be doing the work yourself? The procharger will make more power than a h/c setup but there is more install work and bugs to be lined out afterwards. And if you go the blower route you should pin the crank and since you will need to lower the front rack to accomplish that you might as well throw a different cam in there. 
So my vote for the "best" setup would be for the blower + cam.

Actually on a stock 347 the S/C will *in general* give you a flatter torque curve. Both the S/C as well as the cam setup will give you more UPPER RPM power. Many of the cams tend to not get there "hit" until past 4grand anyways. I know my Torquer V2 didn't really sing until 3800+. If you look at graphs of SC 347's vs Heads/cam 347's they generally have very similar looking curves down below 3grand. With a bigger cubed motor this all gets changed but then again you can always throw a S/C on the bigger motor.....
After having BOTH, I would DEFINETLY say the Procharger. With the Procharger, there's always room to grow (change the pulley), but the stock pulley gets the job done, as you can see in my sig 
. A H/C car is fun, too, but it doesn't make alot of power/torque till late (4000+ on a 23x/23x cam and stock cubes), where the blower car makes power below 3000. Also, the H/C car gets horrid city gas mileage (14-15 mpg) and quite a few MPG lower on the highway(23-24), where a FI car gets above 20mpg city and 26+ highway. (mine gets 20/26 with an auto and 3.73s )
A heads/cam car won't make nearly as much peak torque, nor will it make it all over the place like a FI car will. My heads/cam Vette felt good, but it was seriously lacking low-end, where the FI car will smash you back into the seat and makes torque equivalent to (if not better than) a big-cube stroker-motor.
Not to mention the stock-driveability I now have.
