I spoke with Ron at fiber concepts in Pennsylvania he told me to post on nasty Z 28, to get info on thr clearance we have a 572 GM crate motor in our 73Z 28 wanna know if anyone has used his L88 hood with that set up or even a three or 4 inch cowl hood looking for info so I can order the right hood once also laid at 6 foot level across fender to fender it measured 2& three-quarter inches at the back of the air cleaner and 4 1/2 inches at the front of the air cleaner if those dimensions help any input would be appreciated thank you Also the air cleaner is the low type

A BBC with a performance intake manifold and cleaner will not fit with a flat hood. I ran my 454 with a drop base cleaner with a Edelbrock performer and got away with a 2-1/2" Cowl hood.

Thank you for the reply how much space did you have from the air cleaner to the top of the hood on the inside
The 572 uses a 10.200" tall deck block, so that doesn't help with hood clearance either.
Thanks for the reply we do have a drop base air cleaner just trying to get some input from someone that may have a 572 to see what they did for a scoop wanted to go with a L 88 with Rob from fiber glass concepts wasn’t sure if it would fit so looking for options thanks

I used a 3" cowl hood on mine with a drop base for the air cleaner, using a Holley 4150 on a Wieand Action Plus intake, and the wingnut on top was @ 1/2" from touching the hood.
