Find some 70-71 heads. The 73 and later had low compression. with some flat top reliefs and decking the block .020 you should be up around 9:1 compression. Make sure that you get a good timing cover and have the oil pump gears properly clearanced. select a good cam. TA cams are great but pricey and worth it. Lunati cams are good to and a little cheaper. A good B4B intake or TA SP-1 intake with a holley will give you good power and shed alot of weight from the 50+ lb stock intake.
