I am planning on doing a carbed LS1 conversion on my 1970 Firebird. I am just wondering how much taller a LS1 with carb and intake would be than a stock Pontiac 400.I really would love to squeeze it all under the stock hood but I have my doubts.
Can anyone give me a measurement of how tall a LS1 is from bottom of oil pan to top of carb?

I'm doing a similar swap in my 81Z. Some trial fitting and it doesn't look like it will fit under the stock hood. I'm using S&P mounts. I'll have the engine in soon and then I'll find out if I need a new hood.

On mine, using a GMPP intake manifold and Holley 1000 cfm throttle body, it is about 7.25 inches from the valley cover to the top of the "carb" (where the air cleaner sits). From there my air filter is another 3.25 inches tall. In all, 10.5 inches from valley cover to the top of my Moroso 14" air filter assembly.
Different filter bases can be had for different heights too.
