Looking for a little more power out of a 318

I am in the process of finalizing our build on the little teen for the Duster and according to the Comp Cam Camquest program we should be about 365 hp and 394 tq. That is a far cry from the sad 150/170 hp stock..

She will be .030 bored with gasket matched/pocket ported 302 casting heads with stock size valves, Comp 268H cam, springs etc, an Edelbrock RPM Air Gap with a Holley 670 Street Avenger.

I had the heads cc'ed the other day and they were 59cc's. When we square deck the block it is very likely that the KB167 pistons would make the compression at 11 to 1 or a little more maybe. We decided (with great advise from BJR) to go with the '85-'90 pistons which have about a .025 compression height increase over the stock pistons. We will deck the block for 10 to 1.

With a little more cam 375hp would be attainable but I got a great deal on all these parts including the cam kit. The torque numbers for this little motor look pretty good with that cam though.

Good luck Coletrickle74. I too have heard the 302 casting heads are the ticket for a medium 318/322 build.
