Sully, you are way off base.
What do you want? Shift kits? Transgo 4T60E Jr.
Cams and rockers? Sold by Seriesoneperformance. Come out of the Holden crowd in Austrailia. Know what you want? Comp-cams will grind you one, perhaps even cheaper than the Aussies.
Ported TB'* and LIM'*? Superchargers? DIY with all the instructions here.
Fuel pumps? Walbro. Half a dozen of us have done it.
Underdrive WP pulley? S2 fits if you slightly modify your torque-axis mount.
Pulleys galore at www.pulleyboys.com
What are you looking for?
I've even designed a quasi-intercooler plate that I'm currently testing for thermal flux:
Adjustable shift modultators, Performance PCM'*, etc. It'* all out there.
