Cam breakin question

Yes, I just wasn't sure if "choking" the exhaust with 273 manifolds would affect the breakin.

Then you should be okay! I'm sure you know about the port mismatch, but like you said- it's temporary.
Lol, I want to, but bylaw has been here once already for a fume "violation"...
He would be here for a sound one too with no exhaust. :rolleyes:
Slap those Hi-Po's on there. :)
