Chev R

Hi Kiwi thanks for the input think what you saying makes sense. Just need to sort the spark break now and then back to Dyno. Thanks again

Thanks and I hope they will assist me. Unfortunately had to do mod in there because they never brought R32,33,34 to SA. We can only buy the engine's here or import the car which is very expensive. I would like to own a R34 Gtr Vspec though

Hi thanks man. It is a 1972 Chevrolet 4.1 Limited manufactured in SA and Australia also had them.
