Sounds perfect Mick, look forward to hearing from you.
I'm Running a C4 Auto but don't have a tacho hooked up yet. Having said that the 302 has Extractors, 2.5 Inch System, Electronic Ignition, Redline Torker Manifold and Edelbrock 4 Barrel. The cleveland revs free and strong, i just had the tailshaft reworked and tested it for vibration but 170 was about as far as it would go.
Running an R200.
Yes i seen the conversion that fella in tassie had done. Would be better long term solution.
