Question about fumes!

[Nacho-RT74]

I'm getting this vide up not because the car ( which is amazing of course ) but because something about Mark Worman says around 3:25 min

The fumes makes hurt on his eyes

IS THIS REALLY NORMAL? or well, dunno if normal, but... good?

My car after the stroker build, made the same! Really it makes me cry and hurt my eyes when being around the exhaust! I am, or now, I was really worried about this after heard this from Worman!

Posted on engine section because I have tried everything on carb adjustment to "fix" this fumes "issue"!

Sure my car hasn't been on roads since May 2013, but hoping will be back along next year. I'm building the engine again using another's block after my block was "damaged" trying to square it up for 5th time, and want to know when setting up, this will be ... normal?

My stock 400 never did that, just after the stroker ( around 10.2:1 CR )

Incomplete combustion.

Not good to breath.

Can be caused by several things.

If everything's in the tune is right, depending on cam overlap, it may, or may not be reduced, eliminated.

I remember it, but I got rid of it by advancing the timing so I could have a leaner idle.  Didn't realize the other things BSB67 points out.

That's what I thought... it shouldn't be like that. And Mark Worman is happy with it! LOL

My cam is Crower 282HDP. Nothing extreme.
