CC306 in TPI ...! ok Im about to order a camshaft for my L98 92 Camaro and I decided to go with CC306 cam and dual springs,the car is stock for now but I got LT Hedman hedders,March pulleys and timing gear(for supercharge noise) the car already got Magna flow cat back and MSD blaster coil along with MSD wires the tranny got shift kit and the rear end is LSD 3.23 from factory the Camaro is Z28 25th anniversary 350ci L98 iron heads MAP so should I go with CC306+dual springs+retainers and locks? Suggest the best cam for me please

WAAAYYYYY too much cam for tpi. 230/244 .520/.540. That would work if u got a stealth ram and some decent heads. But you need a cam in the 210/220 duration @.050" range. And actually you dont need a cam yet. You dont have enough supporting mods.

EYah unfortunately that 306 cam sounds great and makes ok power but it's meant to see over 6000rpm. TPI intake does not appreciate anything over 5000rpm. It's a low end torque monster. Extra lift will make more power but a lot of added duration will make for a sad engine. 210/220 like said above is about right.

10 LS Engine Myths That Refuse to Die
Verdad Gallardo If you're having oil pressure problems, a carb is probably not going to be the solution to all of your troubles. Just thinking out loud...
Is the pressure wavering with a rough (nearly stalling) idle? What's it doing when the pressure is low and how low is it?

I know the carb is not the solution but Im taking this chance to get rid of the TPI,when I bought the car the oil pressure gauge reads more than 60 PSI and these days I noticed the gauge get low to 30PSI and the idle get down to 500RPM and when I give it a little gas the oil pressure gauge reads normal but when I let it idle I notice it reads 60 then get down to 3/4 of the gauge then get up to 60 but when it drops its sounds like I got a cam in it
Carb is a cure all for older injection for me, i hate messing with tuning, a LTx or LSx system id worth keeping but not the TPI in my book. Hope you enjoy it and possibly replace your oil pressure sending unit, mine does the same thing but it has never given me an issue.

I told my brother yesterday about the problem he told me is the "service engine soon" came on? I told him no he told me when it does I will convert it to carb so I went home take off the water tempreture connection then I just put it back unplugged so the light came on and today I will tell my brother and I hope my plan works

Dont even think about a cam bigger than .500" lift with the stock heads. For one, you cant go higher than about .470", unless you change the springs and retainers, which it sounds like you are going to do. Second, the stock heads flow terrible, so you wont gain much with a big cam and stock heads. Save up and do cam and heads at the same time. Trick Flow 195's or the new AFR Eliminator 195's are the best heads and what I always recommend for SBC's.
Now, for a mild cam like the mentioned 210/220, a set of Manley 22410-16 springs and 23652-16 retainers will bolt right on to the stock heads with the 1.25" spring size, and allow you to run a camshaft up to .550" lift.
