I say just keep the Savage, aluminum differentials are available on Ebay for 25 bucks plus shipping, transmissions too, other than that, there is not much to break.... You could buy a nice Picco 28 or LRP 28 and a Tsais header with an 086 or 053 pipe and get some real power and still have buku bux left over.
You could have a spare Picco and a set of Fast Lane Machine extended and or lowering plates and still have bux left over!
