The current setup in my '64 Vette is a 327 w/ Edelbrock performer intake, Holley 650, and air cleaner. I'm looking to do a LM7 w/ Edelbrock Victor Jr. intake, NX nitrous plate, Holley 750, and air cleaner. When I put the Edelbrock performer intake onto my 327 years ago I ran into under hood fitment issues and I had to get a '66 Big Block hood. (Not complaining, Big Block hood looks better anyway

). I've never measured the height difference between an old school SBC and a Carb'd LS. Does anyone have any experience with this? I'd really like everything to fit under the stock Big Block hood if possible.
Thanks!
