I just finished building a 406 for my car, but will not be installing it untill after the summer (when the funds come together to beef everything else up to handle it). So in the mean time I want to give my 91' 305 tpi I kick in the pants. I have headers, a full msd ignition, afpr, 3" exhaust, no cat, 4.10 gears (I know there crappy for tpi, but they'll work with the 406), and a 2400 stall b&m holeshot converter. What cam would wake this motor up? O don't mind a rough Idle, but would like to keep it streetable, and responsive! Any ideas? i was looking at the xr269h, the specs on it are 218* intake, 224* exhaust, .495" intake, .502" exhaust, and a 112 lsa. What do you guys think? I will also be switching to roller rockers, and changing the springs, retainers, and locks.

And I have done a search but can't seem to find an answer. I don't want to run a lt1 cam, or any other stock cam which it seems like everyone recomends!

 

Ditch the tpi or run a small cam. If you run the tpi with 4.10's get a 6-speed
