I am looking for suggestions on cam size and duration, I am in the process of freshening up my motor ie. honing, rings, bearings and install a more street friendly cam. I plan on going to the track a few times in 08 but my main driving is to meets and shows. I plan on port matching the intake not sure what kind of numbers the 454R intake is flowing and do some mild work on the heads. I would also like to add thicker head gaskets to lower compression a bit to run on pump gas with no issues and of course still run good times at the track. Thanks everyone:yes:
