Re: L29 454 Build for '63 K15 with NV4500

Haha, caught me sleeping Marcus.

Yes, I had the guides cut down for the positive seals, removed the valve rotators and scrapped the net lash system with the screw in stud kit.

For the PTV clearance, I used a small chunk of clay to check with the head gaskets off and couldn't see through the clay so I ran it as is. Not very scientific I know. It works well though.

I don't have the #s for my cam on hand but it's a Straub 454HO cam IIRC, 530+- lift.

As for an update Marcus, I really think that the 0411 ecm and a good tune would make this thing a beast. Don't get me wrong, it runs great and still pulls like a freight train. I think I've just gotten used to it and think there's a little more left on the table.

I still flogg it regularly. Just hauled 3k# of rock in 2 trips. It pulled just as if it was empty.

Great engine
