If I supplied at no charge the GM adapter boards pre-built for 2 people - who wants to try TBI?

You need to supply the vehicle equipped with a 12V 80A (min.) CS series alternator, the GM harness, TBI and fuel system. Also you would need to supply a megasquirt V3.00 main board and the megasquirt MS2 plugin - all of which can be bought pre-built if you so wish. In order to bolt the TBI on you need a 4bbl intake and a holley TBI to 4bbl adapter plate. To start you can retain your existing ign. system - although then MS would not control the timing. Later you can switch to the '81 calf. HEI dist. and do timing control.

What I ask in return is that you make a commitment to have the conversion done within 4 weeks.
