frknfast,
Why are you using IDA's? You'll be wasting them on an engine like that. I went down almost exactly the same route. I really wanted IDA's because they were on the orginal 40's ,BUT, they are a nightmare to get the best from them. Unless you dyno your engine each time they go out of tune, you'll be throwing HP down the drain! Check out some of the Fuel Injected setups, they look like IDA's, but are so much more user friendly - and once your engine is mapped, its done, won't go out of tune and will give you more HP.
YOU CAN HAVE YOUR CAKE AND EAT IT!! /ubbthreads/images/graemlins/grin.gif /ubbthreads/images/graemlins/grin.gif
