CAMARO6 - View Single Post - What's the real answer on why the LT4 blackwing puts out more power?

The lid makes a difference. Remember it was the distinguishing factor between the zl1 and the v3 where the Cadillac had a squished down lid. That dropped the previous number to 640 bhp instead of 650 bhp.

Also, they did do something with the tune. The blackwing I drove at Laguna Seca idled very smoothly and did not have the normal lt4 intermittent stumble. It seemed a little peppier

Fear not guys, the difference can be made up by getting a custom tune. I’m also not sure it’s worth sourcing a BW upper lid. Maybe can get another but for the money just get yourself a stock 1.7 blower Kong X ported, CAI and a tune and call it a day.
