Hmmm. Hughes engines does a mild porting which enlarges the cylinder volume by 8 cc's. That should give me low 10's compression ratio. Then I can run a hotter cam with a wider lobe separation. Most of my driving will be street. I can give it a squirt of nitrous at the track for an addtional 125 hp or so. It's a manual trans car so idle can be a little unruly. No power brakes or power steering. There is a 408 motor on the dyno page of Hughes engines but I think the cam number is an old outdated number.
