Have you done a biger HEAD & CAM???

im not sure but would a complete rebuild with new gaskets and all, refresh it up nice and then you can slowly begin with the heads cam, etc....:o even a bigger exhaust can help for it to breath better and maybe the driveline, like diff, gearbox.

32/36 webber ( needs adapter ) - will use less fuel than the standard carburetor and little bit more power

350 Holley ( needs adapter ) - lets it breath - lot more fuel - but fun - the cheapest power up of the lot

40 or 45 side draft webber carburetor - one or 2 of - but needs manifold - ( never got around to try'n it myself )

magna efi intake - using magna computer or aftermarket

and then maybe a cam http://www.rpw.com.au/shop/index.php?page=shop.product_details&flypage=shop.flypage&product_id=233&category_id=107&manufacturer_id=0&option=com_virtuemart&Itemid=31
