Me acknowledging that the modern engines have advantages shouldn't be equated to me saying sbm is no good. Or that I disagree with you or anyone. I was just pointing out the ls5.3 I was referring to was NA.... after you suggested it was boosted. Not meant to be an affront to you - just a clarification.
I actually do try to think before I speak. I try to avoid knee jerk emotional reactions in all communication.
Again. A 5.3 L engine, low compression, with a sub 230 deg cam, making over 500 HP. That's damn impressive no matter the brand. If you or anyone wants to take offense to that....well I don't know what to say brother.
If anyone wants to be helpful here...can you or anyone suggest a sbm combo with a sub 230 cam (of any flavor), that will make 500+? I'd love to see the combo. Maybe I might even copy it. After all I am currently building a SBM. Would love to learn something that would help. Or maybe help someone else.
