4 speed action in the dart w/vids

Thats great I love seing other 4 gear stuff. I have a 71 Scamp small block 4 spd Liberty Pro shifted,I have been running a 360 eng W- 410 HP to rear wheels best ET 11.50 119 mph. I decides to spray it with a 150 shot of NOS I could not hook, got 4 passes and put a piston through the side of the block I got worse 60 foots best pass 11.0 @ 123 mph.
Anyway long story short of it I am building a R3 Engine Ryan from Shady dels has built my top end, on papper it should produce over 600 HP to rear wheels and as much as a 250 shot of NOS Q. what should a guy use for a flywheel and clutch. Q. what do you think it will run for an ET.

is it an 18 spline or 23 spline 4 gear you are using? also, pics of this badass scamp would be much loved around here :toothy10:
