Looking for options on the reverse split cams. I want to keep as much low/mid range power as I can with my LS1 build. Ported heads, UD pulley, carbureted setup, LT headers, good exhaust, 3:73, Manual transmission, 1970 Camaro for autocross/weekend toy. I like what I read about the thunder racing 230/224 high .500s 111 cam. What company is making some I can check out?

What are your thoughts about the reverse split cam? Like I said reason I'm interested is I see people making a very very good torque curve and yet pulling great HP also. I'm wanting as much low/mid range power as I can get and still pull strong into 6k. 400+ on both HP and TQ at the wheel is what I'm wanting. What do you recommend?

What is CI?

Hi Zero, I specify a camshaft, one similar to the one such as you ask, ground by Crower Cams.

MY REASON : LATE Model 390CFM Restrictor Class Racing 242/236 .560"/.560 105 C/L
High Altitude operation is another reason for MORE Inlet Duration.

I would like to know more about your requirement ?
WHAT YOU STATE is NOT good for what you ask in reference to your stated needs ?

This is about the only time i can see a reverse split making sense. Maybe it makes sense with a stock LS1 intake and 1-7/8 long tube headers, where the engine can exhale better than it can inhale?

Ok I understand. I would love a 6.2 but it's just not going to happen on this build so my CI is fixed. With that said what cam will get me great low/mid range pull with still making 400+whp? A cam company I talked to said I should use there 224/228
113 Lobe Center Angle with a 109 Intake Centerline
Lift with 1.7 Rocker Arm Ratio: .603"/.595". Do you guys think this could make 400+ on both TQ and HP to the wheels with CNCed 243 heads and bolt ons with a good exhaust running a carbureted setup?

Hi Zero, you state a "weekend" car, NO Day Driving.

This is a "carburetor" cam design for Low End Torque AND WOT engine operation.

I can provide this Crower Cams camshaft.
(Close Centers = Carb Fitment)

236/242 .600" .560" on a 105 C/L

You will need to machine the pistons for Piston/Valve.

I have the GMPP Intake manifold AND the IGN-8 Ignition System with coils in stock ?

Your camshaft has an integral relationship with the flow of your intake and exhaust systems. A very high flow and efficient intake tract will need less duration at the valve than a poor flowing inefficient intake tract. The same is true in the exhaust.

So, when you are choosing your durations for both intake and exhaust, it is all about optimizing your system for the flow demands. If you have a particularly weak intake tract, but a great flowing exhaust tract, a reverse split could be sensible.

Don't get hung up on the idea of the reverse split. I ran a custom Comp 230/224 many years ago. It failed on me and I called Geoff at EPS for a replacement. He designed the TR230 when he worked for that company.

He had a discussion with me that his later testing found a traditional split nearly always performed better in LS engines. He specced me 230/238 cam I was very happy with. At the time they were ground by Comp and it eventually had issues so I replaced it with a slightly different spec Cam Motion 230/238 that I ran until I went solid roller.

If you want a killer cam in the ballpark of the TR230 but non reverse I'd get the Titan IV or something similar from Cam Motion instead.

My first cam was a reverse split cam from MTI.. it was the X1 230/227 591/571 112. It was their most popular cam for guys that wanted a good size cam with excellent drivability.


i made 70 rwhp with that cam stock heads. Look at all the research on a reverse split. It made power.. folks made power with spray and adding heads.. so you cant say it didnt perform.

i wouldnt hesitate to put my old X1 against any traditonal split cam or these new cooler cams... btw.. i sold that car and now have a WS6 with TSP 233/239 and still feel like my X1 would give it a run. I am not saying reverse splits are the way to go.. but i did make power with mine and had excellent drivability.

Uhh, 220/227 is NOT a reverse split.....

Typo.. MTI X1 230/227...
