Room for improvement
I threw the base gasket away and got another new gm one. Couldn't keep this one from blowing out the side thereby not sealing squat! Also the breather tube could use some work on placement and length. Other than that it's doing what I bought it to do and that's look good and feed the 454 what it wants as much as fuel! I would recommend this, yes, just don't expect perfection and check to make sure it's sealed up before ruining your motor.
