What cam should I get?

there are much better cams out there... I had the 284/484 MP cam in the 340 and for just cruising around it was horrible I went back to a "stock"(the smaller Summit cam kit for SB Mopar) and am looking for a bit more now myself wanting to do a cam change and stuff...but that 484 cam aint going back in...for a SB IMO thats more of a strip than street piece. Id look at the Crower 267 HDP or the 271 HDP the 267 is listed as a 273 specific cam plus being a crower it will have /use the Mopar lifter profile.

I believe i got these specs right:

Crower: 267 HDP - 267/271 w 474/485 in a small block - nice lope lots of low end.

271HDP 271/284 485/495 again nice mannered cam. good low mid range.
