Both of my combos made their best power with the 112 lobe sereration set in at 108. The BB 2 xtra lost 60 hp and 75 lb of torque at 112 lobe center.peak hp moved up from 6200 to 6500.rpm.

Re: Theoretical Motor Build Up!

I really can't compare apples to apples here because I was playing with a Procharged 598. I tried 5 different solid rollers, rangeing from 272 to 280 @ .050 intake duration 280 to 288 exhaust. .748...

Re: Theoretical Motor Build Up!

I figured stay at 632 and use a 7.1 rod so you can turn it up, I think you would end up with around a 43 cc dish in the piston. The block isn't available for a little while yet, but it could be fun....

Re: Theoretical Motor Build Up!

How about you start with the new 10.6 Dart block so you can have a decent rod to stroke ratio. Make 9.0 compression so you can run pump gas, use Big Duke 388cc runner heads to keep your bottom end....
