Hi Mikey, trying to run to calculated numbers from a dyno session/weight is almost impossible as I see it, as you have said those 1.7/8" f/wells will kill off some of that, then you got temps/settings and all the rest of what went on in the dyno room on the day as to what it was like on the day at the track etc. etc. You could change converters and pick up 1>2/10ths and so on, I reckon there's mid>high 9.50's in it with more sorting,...if you use Wallace at dyno no's it'll come up with>
60 Foot E.T. : 1.29
1/8 Mile E.T. : 5.88
1/8 Mile Trap Speed : 115.64
1/4 Mile E.T. : 9.32
1/4 Mile Trap Speed : 144

That I guess is something to aim for but think it would need some parts changing out first.

Nice looking car btw....good luck with it
