Cam for super ram
I know a lot of people will say the 219 cam from LPE.
But, will a cam with a 230/244 duration @ 0.050 that will rev to like 6000 or 6500 work well on a super ram?
Reason is, I've had mine to 6300 where it didn't seem to keep pulling before, if I had a different cam would it rev to that RPM, or is the super ram limited to a certain RPM range?

Blk 89 Vette, to answer your question, no I don't think that cam is matched to your intake. It's better suited to a mini ram type intake. I don't know that I'd want to spin any more than 6300 with Hyd rollers anyway.......... just my .02 FWIW

The LPE 219 works because its matched to the runner length of the Super Ram. Over 5500 rpm even the Super Ram dies regardless of the cam due to the long runners.

Re: Cam for super ram (TheStef)
Lingenfelter(LPE) has the "219" cam for sale on E-Bay for $250. This is less than normal LPE pricing (about $325). Remainder of S'Ram assembly(Lingenfelter designed these as co-ordinated pcs.) often show up on this forum or again, on E-Bay. Some say the LPE cam is actually ground by Comp cams but they wouldn't sell an exact spec. cam to me. $250 is about same as Comp Cams would price it anyway. That's about it. LOL

Re: Cam for super ram (black_89_vette)
It's all about where your peak torque occurs. TPI 3200-3600 (depending on heads/cam), Superram 4400-4800 (again depending on heads cam), Miniram 4900 to 5600 (again again depending on heads and cam), LT1/4...well they don't as they are considered detuned/non-harmonic.
If you try to over cam it, more overlap, you'll move the peak torque to the right but lower it now that you are fighting the intake harmonics. The best thing to do is use lift rates to achieve cylinder fill rather than lift duration.

Re: Cam for super ram (ld85)
I asked the same quetsion for the SuperRam... what cam would be best.
This is what I was told and what I found
Sorry I'm not an expert on cam's, but one day when I'll have enough money I'll probably get this cam made for the SuperRam.

Cam # 74219 on the pull down liste.

Re: Cam for super ram (TheStef)
OKay, cool, sounds like the 219 cam is best suited as I've heard before.
Only thing is, I already got gobs of torque, I was hoping to substitute some torque for some hp.
I did noticed the...
74219LP SBC 350-420 219/219 0.560/0.560 w 1.6 rocker 112 CL 1987-91 only SuperRam $250.00
This has the same specs as their regular 74219 cam , with the exception of 1987-91 only, and it is $65 cheaper.
WHy is this?

Re: Cam for super ram (TheStef)
is it hard to change a cam? do you have to take down the intake and heads... or take out the hole engine?
Radiator - Out
Condensor - Move out of the way
AC Compressor - Move out of the way
Alternator - Out
Water Pump - Out
Distributor - Out
Intake plenum/runners - Out
Intake manifold - Out
EGR Tube - Out
Valve Covers - Out
Rockers - Out
Pushrods - Out
Lifters - Out
AIR System - Out
Balancer - Out
Timing Cover - Out
Timing Chain - Out
Then you have to unbolt at least one of the engine mounts and raise the engine up some to clear the front cross member.
Hmm... did I miss anything?

Re: Cam for super ram (TheStef)
since I'm not a mechanic, having this done just in labor must cost a lot of $$$
My GM service manual shows 16.1 hours of work.
