I have for sale camshafts to suit a 4AGE 20 valve blacktop engine. Intake and exhaust with an advertised duration of 292 degrees. I will add a spec sheet tonight at home. They are optimized for a high-compression engine, working above 4000rpm)

Note: these can be used in a 20v silvertop engine, but only with an adjustable intake camshaft sprocket or an offset dowel pin. (there are 5 degrees difference between the blacktop and silver top engines)

They are not able to be used with VVT.

They are in good used condition. No damage to the lobes or journals. Removed from in-service engine December 2014 after switching to a different set.
$400 asking price. Pickup or send at buyer's expense.

Call or txt David on 0415 426 049. (I may not answer at work)
