Hot cams no credit
Strawberry is looking for older photos of the park.
Imagine relaxing in 104 degree mineral water while Steamboat’s famous Champagne Powder gently collects in the surrounding forest.While we were on factory cams, we decided that in addition to the peak power gains, it would be interesting to document things like idle vacuum, cranking compression, and average power and torque gains lower in the rev range.In addition to running the stock cams, we also decided to run a handful of aftermarket Crane cams.Baseline: 5.3L LM7 Cam Being such a diminutive factory cam, it is not surprising that power fell off so rapidly past 5,500 rpm.Run on the high-mileage 5.3L, the stock 5.3L cam produced peak numbers of 353 hp at 5,200 rpm and 384 lb-ft of torque at 4,300 rpm.If you have any photos from the good 'ol days that you're willing to share please let us know!
Here is a common question among LS engine enthusiasts: My buddy, Joe, just bought a new cam for his 6.0L and wants to get rid of his factory LQ9 cam. We wrestled with valvesprings, cams sensors, and differing bolt patterns to get all these cams into the engine and on the pump. The 5.3L used for testing was bone stock, which required at least a valvespring upgrade for the high-lift LS9 and LS7 cams.
The goal of recertification is to evaluate the continued competence of a Certified Aviation Manager.
The intent of the recertification program is to help ensure that the CAM stays current with industry issues and maintains the highest standards possible toward proper management credentials within business aviation.
The three distinct cam families also required different timing (cam) gears and a management system that allowed such hybrid mixing of crank and cam sensors.
Credit the Holley Dominator EFI system for the ability to accept and tune all of the different cam profiles.
We tested the LR4 and LQ4 cams, but these produced identical power to the LM7. LM7Measured out at 6,500 rpm, the early LS1 cam offered 63 hp over the LM7 cam, but the results illustrate that the gains did not come without a trade-off.
