Come on dude. Don’t go there. You aren’t running the horrible cylinder heads and you are not.

So knock off the bullshit.

You know ******* well these 400 plus inch engines with production based heads are nothing but tractor engines.

We are taking about the street stuff these guys are doing.

And yes, race engines start at 8500. Anything else is just bracket ****.
