cant smoke the skins...problem??

If it were in my driveway, I'd first get a compression gage, and do a compression check. The 484 cam is a cylinder pressure killer..meaning it can feel soft if things are not what they could be. Depending on the builder, the pistons may or may not be a true 9:1. My gut says it's not. Also, the MP cams are ground rather clumsy..so you need to use a degree wheel to set them where MP wants them. Advancing the cam a few degrees can also help a little. Also, you know you have to loose the manifolds. Either the $300 A body hipo manifolds, or a set of headers..but they need to go. I'd run cheapie headers. The Avenger model may still need a little tweaking to get right, and BJRs dead on with the chrome box setup. You should have a lot of trouble with wheel spin. If you dont, you have some fixing to do.
