Got 2 cars with my 505 crate engines running into the 10's with hyd rollers.
Pump gas too.
My personal IA combo ran 10.50's on pump gas with my custom hyd roller shifting at 6000 rpm. 3560 lbs. If I would have had the right tranny and gear I think it would have run right close to 10 flat or even 9's.
But it did pull to 7000 rpms without issues. Just when we went to the chassis dyno the curve was flat from 5800 to 6600 then started to drop.
