LA360 Hydraulic Roller Towing Cam

Hey all,
I need a towing cam to go with my 3500lbs Dodge pick-up , for school pick-up , shopping and ski-boat duties!!
I currently have the following going on a local speed-shops recommendation ......
The Howard's quality & finish is amazing !!

Howard's grind no 713175-10
219 @ .050 Intake 225 @ .050 Exhaust
110 Lobe Seperation
but it drinks like my EFI big block dart......!
LA .030" 360 / 365".
This rig only runs on straight Propane
It's has J port heads that are pocket ported that house 2.02/1.6 SI valves , hardened inserts , Comp cams beehive springs & Pac retainers , Crower Collets.
Speedmaster ( I know ) stainless rockers that I'm trying out ,
which have been great with 2000 miles.
The bottom end houses speed-pro hypertecs and pretty much all squared up down there.
No real mods just all cleaned up & de-dagged.
I'm looking at a Crane 699601 Or 699611 what are yawl Haulers running ?
