Swapping my current cam with milder one
Hc or co ? Hi Guard, run your engine when up to temp standing behind your car.
USE you nose/eyes to MEASURE the exhaust gas particle content.
WHEN your eyes "burn" the HC are very high, the chance of a bad tune (not enough fuel).
WHEN your nose senses fuel the engine may be too Rich.
WHEN you have both the Spark Instant may be too great.
Please report ?

The diff cam will be his peace of mind. In reality the 116lsa cam has quit a bit less overlap and will cut the smell. There are so many mechanics ive seen that are super sensitive to hydrocarbon smells so much that they may like how a cam sounds but they wont go near it because of the smell. Go with the cam and you will be happy in your instance. I cannot tell you how many cars come in running like dog crap and smell bad too and the customer doesnt complain about it or notice it. Only after i mention it do they even think about it.

I think its more than that, but really for peace of mind. Youd be surprised how much more a person enjoys something when they dont have the little voice in their head talking about that one point. And how much they will spend to make it happen. In this case its just a new cam.
Its not alot, but if he notices it, its enough. Thats my point. Everyone is different in many aspects of modding a car. like i said, back off the idle timing and ease the smell also, but every tuner is diff also.

Changing to any of those cams is a complete waste of time. The differences wont be noticeable.
A stock cam with longtubes , no cats and dyno tune smells like exhaust.. that`s just the internal combustion engine

Those cams look to have less overlap, less overlap will ABSOLUTELY be noticeable, ESPECIALLY in the area he is concerned with. He doesn't like the idle, the smell, and mentioned the word driveability. When speaking about cams, overlap is the area you go to to change driveability.

With above Id be tuning before cam swapping. A lot of work and cost for a small variable.

But the high overlap could also cause excess HC/smell at idle
