Re: What size pushrods? I haven't measured the ASA cam, but, the ASA cam should have a slightly smaller base circle than the stock cam.
You should be able to get by with stock 7.40" rods, but you will have sightly less preload than stock spec.... No big problem.... Get a set of Thunder Racing 7.40" hardened rods. They are about .015" longer than stock. That will get the preload just about to stock spec.

Re: What size pushrods? Well the stock rods aren't QUITE 7.40". They are actually 7.380" if I remember correctly, but since most pushrod manufacturers dont' make those lengths, the best we can find is 7.40".
