which cam profile would be best? Hello all
I'm doing an LS swap putting an LQ9 into a '95 Range Rover Classic. Off the production line the vehicle weighs in at 6000lbs. With the roof rack and spare and all the goodies I'm weighing in at 6200 right now before the swap to Dana 60's and a rear bumper/tire carrier which will put me in the 7000# to 7200# area. With 320,000 on the odometer it's time for a rebuild of my 4.6l which will only get me the 200hp it had from factory and that would cost $2,400.00 in parts alone and doing all the work myself. To get more HP out of it I would run the cost up to $6k-$8k so I'm doing the swap instead. Got a good used LQ9 complete with all accessories, harness and ECM for $380 at my local U-Pull which leaves me some cash to play with for a transmission, materials to fab engine mounts and adapters (I can weld), new gaskets/seals, a tune, etc.
I am looking at 3 cam profiles. Which one would be best for power and torque from idle to 6k rpm. This isn't a speed demon, lol.
I will be running the 317 heads for 10:1 compression or the 862 with mild port for 11.5:1 compression. Pump gas, no boost upgraded springs.
The cam profiles are:
214/225 .600"/.600" 108 LSA
214/224 .550"/.550" 108 LSA
228/230. .585"/.585" 112 LSA
I won't name the cams so there's no bias. Just the profiles to go by. This stuff is pretty new to me so which would you choose and why?
Thanks

Need the intake centerline to compare. We don't know the intake centerline of the Lumberjack. That leaves the TSP Chopracobra and Trickflow/Sloppy Stage 2. Since the Chopracobra has an earlier intake closing point so it'll make more low end. Also consider the Summit SUM-8728R1 which is a 212/218 110+3 .600/.585. Same IVC as the Chopracobra with slightly less overlap but higher lift. Should have a little more torque and slightly more crisp throttle response. You want to decide on the compression ratio before you decide on the camshaft. The smaller ones will probably have trouble tuning with the 11.5 compression and pump gas.

Looks like I'll be going with the 8728R1 high lift big truck torkinator and the 862 heads. From Summit's response to another question this cam is good for high compression so 11.5:1 should be in the sweet spot. They said this cam is made for heavy trucks. Can't wait to get this engine in and see what this Rover can do with 2.5x the horsepower. It climbs like a mountain goat now in 4 lo with center diff locked and second gear with a 4.6 needing a rebuild. I can honestly say I have never gotten stuck in this thing and in the winter I can do 65 on an icy, snow packed interstate because of the weight. It sits and holds traction like a semi, lol.
