Car is moving like crazy on the big end... your 60' has a TON of room for improvement you can get a half of second off just from there!

Your Mph will come down a little once you hook up good but your ET should improve drastically!

your a 12bolt/9 inch and some Slicks away from consistent 10 second passes!

stock rear 3.42, its always had a bad second syncro keeping me from slamming second at the track or w/e but tranny/clutch is getting replaced now.

It is a little laggy when hit from low rpm but have no problems spooling if i drive it like im racing.

Get yourself a rear, good tires, and a 2 step and come out on some boost. 10s will be no issue as long as you have suspension to put it down.

Ran it on 7lbs 12.1 126 2.2 60' first pass. Turned it up somewhere around 8 and coughed up a rod in 4th around 120 or so. This piece was just sitting on the rack lol oops hopefully have it running again in Nov with forged internals and 14lbs.
