Final report on 526 Stroker + stats & video

what cam are you using? i'm assuming a hydraulic since they stopped the dyno at 5900.

this engine would become a monster with a larger solid lifter cam. it looks like you have a small street cam by the dyno figures.

my guess is you went with a hydraulic street cam to avoid having to adjust the rockers. maybe stock rockers also (non adjust)

so, if you were building for a no-maintenance street build what you have is extremely good. you probably got 500 ft/lbs of torque starting at 2500 rpm lol. you are at 600 ft/lbs for a wide range should be pretty powerful.

dont feel sad about not having higher peaks, since you didnt design peak power into the build. peak is for racing and high rpm's and lots of maintenance.

Your right the build left a lot on the table that can be used with a more aggressive cam but, Sad! quite the contrary, I'm pleased as punch as CME delivered on every specification I ask. I was wanting a stump puller and they built me one. I specifically specified a low rpm street motor with good vacuum, requiring only a low stall converter, and yes I specified a hydraulic cam and dual plane manifold. Don't forget high rpm motors need quality parts and quality parts come at extra expense. BTW, motor is equipped with adjustable roller rockers. I mainly wanted lots of torque down low as that is where my street engine will live. I have a dyno report starting as low as 2850 where it produced 598.5 ft/lbs ot torque. John, the CME tuner/dyno operator, said that it didn't like to load engines down below 3000 but did that one because I ask. Dyno tests at CME are the deacceleration variety, which John said are easier on the motor. They build these strokers up to 650 hp if I'm not mistaken but at that level you no longer have a street motor nor a warrantee. I very happy with the purchase and definitely happy with the cost.
