BTR Truck cams were designed with low lift so GM LS2, LS3 and LS6 springs and pushrods can be used, making these the most affordable truck cams available.
Cam specs are 234/239 .612"/.610" 115+5 and comes a 3 bolt timing gear pattern. The Big Stick of the turbo cams!! This is the one you want if you are looking to build a serious stock stroke engine, or a Mid 6k RPM 408 with something like an S400 Borg warner turbo. Its gone into the 7 second zone in both of those applications. Designed by John Bewley from Lil Johns Motorsport Solutions.
Cam specs are 237/250 .646"/.632" 113+3 and comes a 3 bolt timing gear pattern.
This cam has made 550 rwhp on a 416 using stock LS3 heads and intake. It has been back to back tested on a engine dyno against a much larger camshaft that only gained 10 hp with a Fast intake. The cam timing events allow this cam to be used with square port or cathedral port heads as well as with a Fast intake or Victor Jr. We have dyno sheets available for this cam on all of those combinations. It's a great all around camshaft for a 402-427 cubic inch engine. With 18 degrees of overlap it has an aggressive sound, but is docile enough to be driven long distance if needed. This cam can also be used with a large blower like a YSi or F1R, F1X as well as with 250-300 hp nitrous. Cam specs are 239/254 .624"/.595" 114+3. Many people think that increased exhaust duration kills mid range torque, but in back to back testing this cam makes more power from 3500 on up compared to cams with less exhaust duration.
LARGER DISPLACEMENT TURBOCHARGED CAMSHAFT, 243/251 117+5 This cam has run 4.50's in a single turbo 388, it has also run 4.50's @ 160 in a twin turbo 427, which is at the top of what a hydraulic roller cam has ever run in a 3000 lb door car. If you have enough turbo/turbine capacity, this is the cam for you. Literally the fastest hydraulic roller camshaft for an LS available today. If you are building a 388 to 427 inch cathedral headed LS with medium sized twins or a big single like a GT55 Garrett or Promod. This cam will give you proven performance and reliability for your application.
BTR LS7 STAGE IV CAMThis camshaft is very aggressive and should only be used on maximum effort combinations. This cam has made 600+ RWHP in a few setups, but attention to detail must be paid to attain those results. It has a very aggressive idle, and makes great top end power at the sacrifice of some low end torque. Cam specs are 247/258 112+3 and comes a 3 bolt timing gear pattern. Our .660" Lift Platinum spring kit with titanium retainers work great with this camshaft. Due to the longer pivot length and longer scroll of the LS7 rocker arms up to .660" lift can be used without valve tip damage. We recommend maximum open spring pressure of 430 lbs.
This camshaft is the result of years of back to back testing on 400+ cubic inch engines, mostly using TFS cathedral port heads and Mast intake. The intake lobe made 15 rwhp more than the same exact duration Comp LSL intake lobe, and also made as much power as a Comp intake lobe with around .680" lift. It made more power in back to back testing compared to a cam from another leading cam company as well. So to say that this cam has been rung out, is an understatement. This cam generally runs in the 5.30's-5.50's in the 1/8 mile in a 3000+ lb chassis and has run as fast as 5.10'-5.20's using the same TFS 245 heads and Mast intake. Since this cam utilizes ultra stable lobes, it will turn 7500 rpm with our Platinum .660" lift springs (SK001/SP001). Using our .685" lift springs (SP010-16) springs shimmed to 1.700" it can turn 8000 rpm. Good lifters should be used like the Comp or Johnson short travel and stock rockers. Roller rockers will NOT turn as much RPM as the stock rockers will. Most cam gurus claim .595" isn't enough lift for a nitrous cam, but back to back testing has shown otherwise, with increased exhaust lift showing no gains in power. This cam has gained 400 rwhp on a 300 shot of nitrous utilizing TFS 245 heads with the N2O exhaust port. Cam specs are 251/266 .63X"/.595" 112+4
This cam has the same specs as our very popular LS3 Stg II cam, except with 3 degrees more advance for increased low end torque. Since the timing on this cam can be retarded via the VVT mechanism it will make the same or better peak power than our non VVT Stg II cam giving you the best of both worlds. 225/238 612/586 113+6
GEN V VVT Non-AFM 22X/22X .60X/.60X 114+6 Stage I camshaft with stock fuel pump lobe. This Stg I cam is small enough to use in truck setups, but big enough to make great power gains in any Chevrolet Gen V engine application. A torque converter change may be needed in some L83 applications.
Custom LT1/LT4 Camshaft for Supercharged applications. Includes optional 38% increased fuel pump lobe. This cam has made over 900 RWHP in the famed "Blue Dragon" C7 LT1 using a F1A supercharger on 15 lbs of boost, Land speed CNC heads and Stock injectors. It has also made approximately 1100 RWHP in a C7 Z06 using a F1R supercharger. With one tiny degree of overlap this cam is mild enough to be used in daily driver applications. It can also be used in positive displacement supercharged applications like the LT4. This cam is also mild enough to be considered a "Stage I" style cam in a naturally aspirated application. Cam specs are 22X/24X .63X/.62X 116+6 using stock 1.8 ratio rocker arms. This cam is easy on parts.
