Sixpack on a 318 engine ?

roaddevil said
okay i stumpled aver this Six Pack and the price was right. I know a 340s would be cool but the only thing i have is a 318 which i plan to rebuild the cheap way. Hone it, , new rings and so on, a basic re reing job.

What you guys think, is it a bad idea to use the sixpack in this ? And if the answer is yes , what cam should i use?
Car will be a 66 Barracuda with a 904 automatic not sure about the rear end ratio. Converter stock.

Need a 340 cam or a tich more. Port the heads and use inexpensive LS 5.3 valves. 1.9"/1.55". You do need to install either the LS powdered metal guides or bronze guides, with the 8mm diameter. That also opens the door for beehive springs, retainers and locks.
Go for it, only 22 CID difference. Just need the port flow and velocities.
