Q What compression is this motor at? answer now
Asked by Jacob on February 26, 2024 9:06 pm

A Compression would depend on the finished chamber volume of your cylinder head but could range from 12.5:1 with stock unmilled 59cc chambers all the way to 15:1 with our CID heads milled to 45cc chambers

Hello , I have a camaro ss and it’s currently sitting at 570 hp and 500 torque being FBO with a Hi ram , E-85, ported heads and stage 3 cam. I’m wondering if getting this stroker is worth the money and also would I have to get new heads ? How much hp would this stroker add?

A Guessing you have a ls3 motor already? Heads and stuff should carry over. Bumping up your compression will help power through the whole rpm range. Bump the compression up to 12.1 roughly and you'll see the best gains with E85. Should get a different cam. Give them a call and spec out your build needs. I have a ls3 I'm planning doing a 416 also.
