Jerico built for clutch shifting so it won't pop out of gear. You can still shift clutch less WITH the proper clutch assembly & clutch tune. I'd recommend the "Sportsman Dual 7"; google it or email me for more specifics. You want a small diameter clutch for that little 283. It will go much faster than a larger single disk unit (McLeod's is 10.5"). Total weight on the dual 7" for a SBC is around 18-19#'s, flywheel and all. The dual is not only faster, it will be more forgiving on the tune than a single disk is when trying to optimize your ET. Then when you want to drive it on the street, tighten up the base pressure (less than 15 minutes) and go to the burger joint.
Jerico - $2500+/- used.
Sportsman Dual 7" = $2900
Long shifter - $500 +/-
Browell bellhousing - $750+/- with window for easy adjusting
Or I have a new SBC bellhousing from QuickTime Inc I'd sell to you for $450. Both the Browell & QTI are very lite-weight compared to the old Lakewood hydro-formed units.
I gotta think you would easily go 10.40's with that car. Again,easily 10.40's!
