The 306 grind has been around since before the birth of father time.

Does the stock oil pump have to be changed when doing this swap? No right?

In my experience, I don't think it was the cam that killed my stock bottom. The cam was harder on my valve train, what killed it was me spinning a 140,000+ mile engine to 6500 trying to use the available power the cam offered. I spun a bearing in just over three weeks.

pretty solid set up, but like what the others have said LE has some nice set ups, and AI also has some nice set ups for H/C combo's. look into packages, its a lot cheaper than parting this **** together, trust me lol
You just gave me inspiration to run nitrous after my cam swap

Saw a CC306 and GTP Heads dyno 429rwhp through an 4L60e and 9" in a 355, so it's definately proved it self over the years on at dyno and at the track.

That being said I ran a CC306 in my stock headed LT1 for a few years and I enjoyed the cam alot. Just make sure you get some gears and a healthy stall.

I love my CC306, sure it's old but it's great. Only thing I need now is a 3600 stall, I'm currently running a 2600 ish and it could use a bit more ***** on the low end. Not so much right off the line, but from around a 20 roll.
