What are your thoughts on this blower cam?
Custom ground cam I came across. Bigger than what I currently have. Building a 383.

The duration is solid roller huge but lift is kinda tame. 26 degrees of overlap which is too much.
I run a LE 226/239 w/114 lsa which only has 4.5 degrees of overlap. Hydraulic roller 383 with peak power around 6k.

Here's the spec's on current cam that I have.
I thought that one seemed off spec for a blower cam so I Figured I would ask on here. Thanks for replying.

Yeah that other cam is huge and would suck to drive. Would surge plenty down low and bleed off boost.
Your current one isn't a bad blower cam for mild boost. 6.5 deg overlap and probably drives nice on the street.

That cam would be for a big engine with lots of boost with a focus on high RPM only (6500-7500 RPM) with LOTS of boost (20-30+ PSI) or someone tried to make a "band aid cam" where customer had too much compression (11.5-12.5) but is insisting to running lots of boost and this is just what it will take to keep from blowing the heads off the engine but it will still never make power like the correct cam and forget about any low/mid range TQ and/or drivability.
It might be the 'right cam" for the set up it was designed for but I can't see that being the exact same set up as anyone on this forum would be building. Even if it was a "close to" a set up that needs such a huge cam, a build like that should have "new cam $$$" in the budget instead instead of trying to save $100-150 and having the wrong cam in their set up.
