Let's debate this cam for a PT88 370ci turbo build.

I am thinking of trying out one of those Comp LSL lobe cams. I'm thinking 231/231 .624/.624 115+1. I like the look of it on paper for a front mount PT88 370ci build.
Details:
LQ9 Iron Block (370ci)
4.030 Wiseco 25cc dish pistons
Stock Crank
PT88 front mount turbo
AFR 225 heads w/ 60cc Chambers
Truck manifolds
(2) 2.5" pipes into a T4 flange
4" DP all the way out to right before the rear axle
TH350 transmission with 4200 or so stall
S60 rear with 3.55's
Would love to discuss the pros and cons of it. Open to suggestions.

Looks like a good cam, on paper like you said, the lift is a little high for my liking but if its not a daily, f*ck it! LSA sounds good too. I also have a 370 on boost but I went with a traditional split 232/240 .595/.608 115, mine is almost a daily driver and I am very happy with this cam so far. Get some good springs and valvetrain to handle that lift and you should be golden.

Is yours a front mount?

My set-up is rear mount, daily driven with some track. I would think the 408 would like that crane cam much more than a 370. The 231/231 .624/.624 115+1 your looking for on the 370 sounds good, I'd just check the valve train more than routinely on that kind of lift.

id bring the lift down some like .020 my friend mark was making 1200 wheel with his front mount with about .600 lift. it would also be alittle bit better on V-train down the road. give the spring some room to handle the boost as well as the valve
just my .02 cents bro

Maybe I can consider going to a 232/232 .595/.595 on a 113 (XER Lobe). The reason that I originally spec'd the .624 lift cam was because I was running the same lift Crane cam in my 408 and these are the heads that I was using for that setup. It was a great performer for what it was. Since the AFR 225 peak out at about .595 lift, a .624 lift cam would keep me in the higher flow numbers more of the time where as a .600 lift cam would spend more time in the lower flow area of the heads. I also don't intend to spin this thing above 7K RPM. I will definetly take it under advisement.

IMO, you cant do a PROPER build thread and not include the cam specs. It's just incomplete.

I just figured that he did secret cams like some of the other guys on here.

I would stick with a 115 or higher LSA, I used to have a 112 LSA cam a while back and that thing would bleed off between 1-2 lbs of boost. Never had that problem after going with a higher LSA cam.

In my old 6ltr. motor(377ci). I had a comp cam. It was a single pattern cam. Specs were 605 lift and 240 duration@50 on a 114lobe sep. I make the most of 1089rwhp with this cam and it sounded very nice as well. I would raise your duration and lower your lift a little. You want the valves to stay open longer to let the exhaust exit for the turbo and the intake charge fill the cylinders with as much forced air as possible.
