has twin carbs ones that sit up right not the sidedraft ones
You mean the twin down draft carby's ? - Do you have an inlet manifold to suit that ? (came off a 3K-B)
Extractors are good. Are they Customs? 4:1's ? 4:2:1's ? - they are so much better than the stock POS exhaust manifold.
Lumpy cam... ehh unless the previous owner / builder has the card that came with the cam when it was done, i woudnt know what cam it is or how to find out.
Rule of thumb. 4k block / bottom end + 3k Head = 10.0 : 1 Compression (where as stock 4k motor is 8.5 :1 / 9.0 :1 - can never remember ) - Its a quick upgrade. If you want even better results, track down a 3k Bigport head - its basically the same as a stock 3k head, but its got much larger ports, and a Welsh plug at the back of the head (welsh plug = keeps coolant in motor... in simple terms)
Are you wanting to stay NA or go turbo / supercharger ?
