1/4 mile. Ben is the LS engine swap guy to go to, foreign or domestic. Unfortunately the 9 sec. engine blew and the replacement is only doing the low 10's and 136 mph, so far. The Sunbird is Pontiac's version of the Chevy Vega.
He is also great with the SVX (with learning thanks to you), if I am able to schedule some shop time.
