Oh yea, 1/2 aluminum line to a chrome "dual feed" cheese-ball deal...motor looks like it MIGHT run in the 11's... 6156670-Kens_416.bmp (55 downloads)

Still has leafs and it's a stock body except the glass hood/deck/bumpers. We think it's a GREAT 60' car...it looks best 60' away!

We dynoed it with a 750 Holley, A stock 800 cfm Thermoquad, and a brand new OTB Holley 950. The 950 made the most power by 20 HP over the others, 525HP/510TQ.

I started with a 750 on that one then went to a 850, 950 and finally a 1050 dom... if I had a 1150 I would try that also..... BUT I launch off a trans brake and that makes some difference... I dont need the real fast low end response (mines pretty darn good) but the smaller carbs will be a little faster on the low end response
