I actually just got that particular cam for my 91 L98. I have the TPiS Bigmouth base, SLP runners and a ported plenum (on the intake side) and long tubes into a Corsa cat back (on the exhaust side). The guys from their tech line said that was the best bet for those particular mods. I too have the stock 113 heads which, according to them, will support all of the above mentioned mods. I haven't installed the cam/intake setup yet...just gathering parts now. Now you've got me thinking

 

The 08-502-8 (aka CC502) is a better choice for you and the OP. It's rpm range for power production better matches a TPI setup (even with SLPs). The 503 will still work but you're giving away a bit of low-end torque w/o gaining much (if any) top-end. TPIs just won't "allow" it. A CC501 cam wouldn't be a bad choice either -- better than a 503 for a TPI.

I never like anything ANY of the comp techs said to me on the phone.

 

Per the MK 82 cam thread 5° duration was what, 3 hp? 224 int dur compared to 219 as an example. You could degree it in for lower RPM use.

 

You could but why?

 

 

My car with cc502 ans HSR made 268HP and 315 TQ on a screwed up dyno run. I think it can make more.

So you'd install a 108 ICL cam at 104 or less? (FWIW, I'd grind a custom cam if it were me.)

 

So I Should wait and do the heads cam and intake together.
Thats kind of what I figured but my budget kind of dried up.
So if I wanted to improve on what I have.
You recommended the accel 211 cams & 1:6 rr's
is there another cam you can recommend that would work well with the stock setup? I just want to have a couple of options.
thanks again.

 

the cam you suggested is to agressive for stock ECM you WILL NEED TO BURN NEW CHIP!!
however i have used this cam with noticable power gains comp cam 20-810-9 Xtreme Energy™, XR268HR-10 basically hot cam (ZZR)
Street Machines, Stock Converter in 340 & 360 .. use it with 22-2400 stall convertor,, modifiy tranny with shift kit , shift module for tight smooth shifts, (if sundrum hasnt been done, you may break IT) . regular 113 ported heads, modify the TB as suggested in prevoisly post. make sure the play in the butter fly shaft is gone.. ..DONT USE 1.6 rocker WITH THIS CAM, excedes max allowable sping compression which is .500I and .500E.. 1.5 RR S/A narrow bodied recommended ,change the rocker stud bolt to ARP 3/8", change valve spring as per comp suggests. CHANGE OUT THE AIR PUMP ..with ELIMINATOR like in my avatar ..this combination will give you noticable seat gripping power where your buddy will be not able to grab the 100 dollar bill , from the dash, when you open er it up!

the above combination work well in my 87 l98

stock valve cover will not work! the RR lock nuts are too high .. use an chrome steel center or aluminium cover ( grooves cut in for looks)which slighly higher then stock,(tall cover dont clear the air condtioner bracket) these still need to be modified by machining the inside support down to about 1/2" . this is done to clear RR and locks.. leave the tighten towers intack

 

you need more naaawwzzzz!

 

Well TPiS ZZ9 would work with the stock or modified TPI setup pretty good. Its not all that different from the Accel 211. Anything you go with that has similar specs to these two cams will be just fine for a TPI engine. You tune it for those cams, and then you can do alot to the intake as money comes (bigger runners, base, plenum porting) and it wont need a retune again that badly.

Now if you were going to switch from TPI to SuperRam/MR/Stealth, then it will need another tune.

The reason why I recommend to do it all together, if its possible, is because the tune can be customized just once that way and you won't have issues. If you do heads/cam first and tune it (as you should with a cam change) and then do intake later, you may need a retune and depending on who does it for you it may cost you the same $$$ again.

 

I have been thinking about it

Maybe I'm doing something wrong but...
I punched that part number in and it's telling me it's a Mopar Cam.
