Nicks Garage 383 build

Spoiler alert!!!
If you don’t want to know anything in part 3 before you watch……scroll on past this post……





1- I wouldn’t consider any of the valves in the old heads to be “sunken”.
Imo, it’s a non-issue.
That being said, almost any 906 heads that come into my shop get hardened exhaust seats installed.
So, put in some seats, do a nice valve job, and a mild bowl blend.
No one can tell if the ports of the heads have been touched by a grinder after they’re installed on the engine. But the seat of your pants can.

2- fly cut the pistons while still in the block.
I did it to my 383, which had negative .010” intake clearance on the intake side.
Not a big deal. Aluminum chips? That’s what the vacuum cleaner is for.

3- I wouldn’t be surprised if the 346’s end up making more TQ. Not so much because of the less sunken valves or the cr increase, but also because ootb, the intake runners are about 8cc smaller(which could be helpful on a mild 383 with exhaust manifolds).
That was a test I always thought would be fun(but never found the time).
906’s vs either 346/902/452’s………equally prepped.

4- while he was messing around off camera with the aluminum intake, he shoulda bolted on some small-ish headers.
I bet they would have been worth more than the intake was.
Especially with the Bullet cam.

5- it’s his channel, so agree or disagree with the plan of attack…….he gets to decide how to proceed.
