Do you know if they installed a cam button? I see that washer welded to the timing cover.

Did they dyno it?

The engine has been broken it, but no dyno. No cam button that I am aware of. Flat tappet cam.

I liked Nick and was sorry to hear that he passed. I hope the business is going well for his son now.

Nick was a good dude, I enjoyed talking to him on the phone.

Had to replace a bad block for him once,
and that replacement resulted in the machining program being changed.
I wonder if the current block supply chain has any idea of that tweak, but maybe I shouldn't want to know.

Nice build!
Is that a standard port intake ported to max wedge size? If so, who did it and how much?

Excited for you!! Should run great!!
Loved Nick Sr. I live around the corner from him. He followed me home in the Dart one time to make sure everything was running well. Nick Jr is a chip off the old block. Super solid guy

Yes, it is a standard port intake opened up to max wedge. Nick Jr. did that for me when he built the engine. Not sure how much it cost since I had the whole engine done over there.

Thanks! I’ll probably be doing the same.
