Hello all. I am seeking to replace the stock 402 big block on my 1970 Monte with a ZZ502 deluxe crate engine. The intake manifold profile with Holley carb on this crate is higher the stock OEM manifold with Qjet carb on the 402 and I am concerned that the 502 will not clear under the non-ss hood. I am wondering if those out there with a ZZ502 deluxe under their hood have had clearance issues, and if so, may height issues be solved with a Holley dropped base air cleaner bottom and/or a 2 inch tall air filter element in an open air cleaner assembly. Thanks all, Barry T
