Well, usually if you run 1 pass on a combo & it goes 11.12.... You probably have a 10 in it with some more track time LOL Cars rarely run their best on the 1st pass off trailer... MPH is just hair low for ET I agree. Could be any # of things from air cleaner/hood scoop/airpan issues to fuel delivery, ignition etc.

More passes are needed for more data, before start speculating too much. My Road Runner runs 120-120.7 MPH @ 11.24-11.33 normally, & even then I still feel it is hair lazy going from 1000-1320, it lays over just a hair, I think it's on verge of fuel with stock 5/16 line & mechanical pump. I could spend days trying to fix that little top end issue to find hidden 1 MPH or so.... but not worth it, for street car.

I'm glad it's working better for you, especially now that the piston rings are right side up I'm sure you'll either get a 10.XX out of it with little more time on it, or you'll get kicked off track for lack of rollbar by that time.... LOL
