Used to be that '5 blade' automatically implied Warp; not so anymore. What kind ?
68 sounds short to me, but I guess that could depend on what kind of blades they are.

I prefer wide blades, but there is no denying how successfully Sidejobs ran a 72" 4 blade Excalibur. Image

If you're talking about a warp drive or a saber/razor, I don't think that would be enough prop. I prefer something between 72" and 74" on a caddy, preferably a two or three wider blade prop.

Agree with Deano, it helps that he knows Caddy engines also, it isn't a junkyard pull..... I had an 8 blade warp that I alternated pitch, 4 high 4 low, worked real well, basically stock motor, common build ups like intake plenum, roller rocker shaft, etc. wasn't a hill climber but I never got stuck. no a lot of dry runnin here in NW Florida.
do it right or dont do it at all!!

if you already have the prop bolt it on and give it a try before you spend money on a different prop.
