Be careful with the heads you get if you use the Superram. It has smallish ports and WILL NOT fit on many of the bigger runner heads, (like the fast burn), without extensive modification.

I leaning towards the stealthram anyways...Im probably going to have to changes heads anyways...I have the Edelbrock Perfomer RPM's.....but Edelsays they will work fine with the stealth........Im also going to change the cam thats in it now...is the stealth easy to install?..looks like it..
I need to get going with this swap...Im tried of driving the beater V6

with the RPM's that a stealthram produce...will I even use that on the street?....I dont want something thats going to be a lug down low unitl I get up in the RPM's......most races are won in a holeshot....and on the street most of the time its froma roll.....so will the stealthram give me what I want?

According to Holley's WEB site they have stealth ram intakes from 300 to 670hp. So I would think there would be one you could use. I have not researched this intake, so someone else will have to chime in.

I have the StealthRam on a 383 and it doesn't lug down low in a RCSB truck. I am using AFR heads as well. Its a nice combination but its more for the mid-range to upper power band whereas the SuperRam is for everything.

do you still have alot of lowend power?.....spin the tires if you wanted? of course I'll be using my 300 stall thats already in the car...when do you start making most of you power and where does it start to fall off....rpms that is...thanks!

Re: superram or stealthram on a 383?
Yea I do b/c I set it up for that as well...for the torque that is. I have the stock stall and don't have a problem rolling them over but if I was to put a 3000 in it....it would be really fun but waiting for my tranny to go now. I starting making the most power about 3800 rpms. The torque is nice and flat across the band but at 3800 rpms, it will sit you in your seat. I've had it up to 5500 rpms and it is still pulling...the stealthram system love rpms....most people like to rev it to about 6k or 6500. Right now, my setup is for about 1300 to 5600.

If your switching to a HSR you will lose torque and low end w/ a stock tune. I didn't notice any loss of low end by switching from a siamesed runner setup w/ a good tune to the HSR w/ a good tune. Thats the key in lowend on these cars is keeping a good tune to compensate for the additional airflow.

thanks!
thanks!
I took it to the dyno once and it hit 15:1 AFR when I was at 4100 rpms with a custom tune and I decided to shut it down...didn't want to risk blowing a piston or anything going lean so took it off and been tuning ever since. SOTP, it feels 10x better but anyways, I was already making 260rwhp and 330 ft lbs of torque. Peak power is supposed to be at 5500 rpms so you can see what my combo has left in it. I am expecting 330-340 rwhp.
