9.2:1 and it runs great on 92 or 94 octane. It really made the motor than more responsive and just seems to run that much nicer since it has been boosted. the motor is out of the car now and getting a treatment of some new headgaskets, new arp bolts, removing the cast marks in the ports on the head and intake manifold. just a slight gasket match port job. and some fresh powdercoat since have been building a little powdercoat workshop in my garage.

To be honest if i could have done the cast iron manifolds i would have. I think they do better with the heat and when coated they look great. If you make a set make sure you make them out of 304ss or 316ss. 321 is another choice but real exspensive. i am going to ceramic coat mine for the added pertection from heat and corrosion. what do you think about the torch red with the carbon fiber bumpers? or maybe some modern gsx stripes in carbon fiber? i think i might start looking for someone to due a rendering of the car.
