I presently have a 376/480 that is stock with the exception of 1.75" very long tube custom built tri-y headers and ported L92 intake.

I was using a TCI 2200-2400 RPM stall converter. I am changing the transmission and torque converter to a very high-end GearWorks TH400 off road racing transmission (trophy truck level) and a 3700 RPM stall Coan/GearWorks torque converter. The transmission has a 2.80-2.85 low (can't remember exact number). I have 5.83 front and rear ring & pinion and 3:1 transfer case, 37" tires and a 4700 lb vehicle.

I have new Katech/PSI springs beehive springs, TI retainers, Cadillac racing lifters, Katech C5-R timing chain and Trend 7.40" pushrods.

The kind of racing I do is mostly in the 2000-6500 RPM range. On rock climbs the motor frequently is bouncing off the rev limiter up to several minutes. In desert sections you are constantly on and off the gas and accelerating and decelerating.

I have to acquire a cam in the next week so that it can be installed the following week and dyno tuned. So I have a real tight schedule.

I was thinking about the old ASA cam to replace the old Hot cam. (I do know how old the ASA design is) The ASA will give up some torque especially below 4000 RPM. I considered the Katech Torquer as well but it looks to give up about 30 ft-lb torque below 4000 RPM as well. And the Katech dyno test was with WCCC CNC heads and 1.875" dyno headers. The COMP XER cams' lift concerns me with their high lift and what the PTV might be. My heads and pistons are stock at present.

Any recommendations on a cam for my application that will maintain a nice comfortable PTV. Obviously I am not concerned about streetability and wide LSA. I am after HP, torque, and good PTV.

Thanks.

 

With that RPM range, just to give you an idea, I made 484/444whp/wtq in a 14 camaro(stock ls3) with a Cam Motion cam 232/238 .620/.603 113LSA(titan vi), 1 7/8 headers and cat deletes, and adm intake. Car made 400wtq at 2k rpms. I'll see if I can find the dyno sheet.

Car made 376/376 bone stock on a dynojet. Numbers above were on a different load bearing dyno. I cannot remember which kind however. I want to take it back to my buddy's shop with the dynojet and redyno on the same dyno to get a true reflection of power increase.

 

I am installing a new motor in a rock crawler at the shop right now. 403cid with cam motion .639/.638 lift with 232/240 duration 112lsa. made 577hp at 6200 and 553tq at 4600 with over 475tq from 3k on up.

 

I hate 2 sound rude or beat a dead horse, but if YOU truly want a good cam recommendation call one of the good cam guy's on here. Transmission/rear end gear/ weight of the vehicle all factor in your cam choice. 1 phone call and you take all doubts out of the game. You can even have it tailored to you specific build at no extra cost such as engine size, intake being used, head flow and other things etc....compression ration.
You will also get what valve springs that are recommended for your particular cam spec's. Pick that phone up:-)

 

Get ahold of KPE out of Texas, he has an LS based trophy truck.

 

Recommendation taken. I will be working with Tick (Martin) for cam and new TFS/TEA heads.

I have had this on the back burner for the last few months. So now is the time to go.
