Edelbrock Heads for 318

So its NOT a 318 then, I still don't understand why not a 360 stroker thats like a 408, still 18 CI bigger. ATI trans has their own crate engines now and a 408 chrysler is $4,996.00 and its 450HP at 10-1 comp. Comes with a 12 month warranty. Fully dynoed and cam broken in. Just drop it in and drive away. Not sure if its online yet, wasn't this summer when they first came out. www.atiracing.com Don't see it but its in their catalog, its has all new valves, hyper pistons, new oil pan, sounds nice. The race motor has forged pistons but 11-1 comp. makes 525HP and cost $6,996 again race only
