Funny thing, an engine builder here, who apparently knows nothing, sent me a custom grind roller ([email protected], .650, 112LSA) Wonder why he did that?? Definitely wasn't to improve my idle quality, octane requirement and street manners....
yes, his selection will indeed improve idle quality. On most “ head limited” typical Mopar bracket combo’s I have found narrower to go down the track faster. That said, higher LSA likes more compression and convertor to get it to leave.
I swapped out a 107 cam( Dwayne did for me) for a 112 cam a cam guru who knew me and my combo and said my car would be faster. Knocked about 1.5 tenths out of it, killing my 60 foot. This was an 11.5 compression flat tappet W5 deal at the time.
You will most often( at the track) see wide stuff on power adder combo’s or stuff like pro stocks..which have tons of compression and great heads, or stuff with lots of inches good heads, and compression
