Does he want an easy driver? Something easy to operate with a clutch? The 110 LSA isn't to bad at all, dropping down 4*'s of duration will be more torquey where it counts for a driver. A wider LSA would be easier on the clutch operation. I've driven my 4spd '73 Cuda with a cam on a 108 LSA. Its a small learning curve. Being the cams idle vey differently between a 112 & a 108.

The reasoning for the duration is based on my 408. It has a Procharger on it and it has a 228* @ .050” cam / 114 LSA and it drove great when not under boost with the TKO and hyd. clutch. It’s setup with about 7 lbs of boost. I know it’s a 4” arm in mine but I would like to see what it’ll do with a 3.58” stroke with a 110 LSA.

I have a 340 / 4 speed that I’m about to get running in a duster that has a Comp Cams 224/224 cam / 108LSA so we’ll see how that shakes out.

I like a wider lobe separation. Like you said @rumblefish360 they do come off the clutch nice for a driver.
