Re: Reverse Split cam vs Standard cam?
Don't quote me on this, but I think the duration on the exhaust side is more, as in open longer. It makes up for a free flowing intake and a lesser flowing exhaust to equalize the amount of A/F entering the motor and the exhaust leaving the motor. I'm pretty sure this is what reverse split means, but not positive. It's either this or the other way around.
A standard cam is both the exhaust and intake duration is the same.

Re: Reverse Split cam vs Standard cam?
standard split is like this 218 intake/220 exhaust
no split is like this 220 intake/220 exhaust
reverse split is like this 220 intake/218 exhaust
the reverse split helps make up for an intake thats more restrictive than the exhaust.

Re: Reverse Split cam vs Standard cam?
Single pattern and dual pattern. I've never heard of standard and split.
standard... refers to standard split or traditional split... having more duration on the exhaust side.
reverse split is more intake than exhaust.

Re: Reverse Split cam vs Standard cam?
Can someone explain me pros and cons?
Another good use for revers split is on turbo applications, on a 114 lsa of course, why, b/c it raises the exhaust velocity, you want to have a bottle neck in the exhaust that away it will turn the turbo faster, and boost up quicker.

Re: Reverse Split cam vs Standard cam?
when looking over cams, i have always felt that traditional split cams make up for the fact that your exhaust valves are smaller than your intake valves, and usualy there is a 40 cfm difference on stock heads when comparing intake and exhaust. IF you look over it, therre are 100's of opinions comparing the two. But for nitrous you need more exhaust duration. Single patterns do idle a whole lot easier than the split's. I stuck with a split 228/236 .570/.580 112 cam, it is a standard split, and is known to be a good midrange torque cam.

Re: Reverse Split cam vs Standard cam?
ok sorry about the double post, but from what i remember, the ls6 intake is not a limiting component as long as you don't have heads that flow over 280 cfm, it's for the s2 head guys where it's limiting, hence why ls6 heads flow around 275 cfm at .600

redz 02....please post your dyno results. I have been looking at that cam, but w/ XER lobes. What lobes are using? XE? If that lobe works....I will definitely go with the lower lifts.

Re: Reverse Split cam vs Standard cam?
They are XER's b/c the lift is to drastic for an XE, at least i think. The cam is a G5X1, bought it from BigSS, he pulled 407 through a 12-bolt on an M6, with hookers, and i think a pully in a 00
" SS. Haven't had a chance to put it in, car is in the body shop and i just got my LT's so as soon as the car is out, it's time to hit the garage. at 416 what cam are you running, sounds like a beast. Personaly i would go with a standard split or a single pattern, i have heard that the reverse split cams are peak cams, not as good at midrange.

Re: Reverse Split cam vs Standard cam?
A reverse split on an LS1 with headers, good Y-pipe and cut-out will produce almost as much power as a traditional split but will have better idle and very low end drivability by virtue of its lower exhaust duration overlap.
reaon I am asking is that I have a 228/224 with macs and Y
going to go with a larger traditional split and true duals...
will the duals be worth it I guess is what I am asking??

Re: Reverse Split cam vs Standard cam?
redz_02....My current setup is TEA 5.3 heads w/ a TR224/114. It is a blast to drive to say the least...but am very curious about swapping a big standard split for my current stick. You mentioned that you thought the lobes were XER for lower lift??? XER lobes have higher lift than XE...so I think you have that backwards. I have been considering an XER lobe on the intake and a XE lobe on the exhaust to keep the lift down a tad. I like the 580ish range to help with wear and exhaust scavenging.
