With that 60' time, if it would launch good, it would be a LOT faster.



Good run and good looking 'land yacht'

Thats running very good on the top end. I think that 6.59@108 will get you in the 10.30s in the 1/4.probably in the 135 mph range.

No tubs and a 12in wide 750 series Sander wheel with 275/60 radial pro rubber at 18psi.I put hi-tack on the beads to help keep from slipping. no beadlock and one of my tires moved on the rim about a inch.see the white mark?I believe that 6.59 run was 13-14lbs boost.I'm using a treadstone #1245 innercooler.

That first pic of the engine is a mirror image.still try too figure this damn picture problem i got.

All that car needs now is a flawless coat of shiny black paint.

Nice work, -Abone.

Paint don't make it any faster,but your right,it needs a nice paint job....the 7K3 heads are original to this car and have stainless valves,10 degree locks,lash caps and Teflon seals.Butler street ported these heads in 98.I had Butler freshen them up and spec springs for the Butler hyd roller turbo cam.my built on this engine is in the boost section a couple years back......Charlie the turbosmart
Hypergate45 has worked flawless.I must have did something right....thanks
