ZZ383 install surprise in my 78
Today I decided to see if the stock hood would fit with my new ZZ383 install.
Well it fits with 1/2" clearence. I was expecting to replace the hood. All info stated ( will not fit under stock corvette hood )
GM ZZ383 with Eldebrock 7516 air gap, and used a 1.5" drop base GM 3" air cleaner.
The GM Serpentince belt system installed with a few mod's just waiting for the dual fans.

Your using a drop base air cleaner.... Most threads state it may fit with a drop base air cleaner. also the different year c3 hoods had different amounts of clearance... you appear to have a lower setup than I do with my drop base 3" cleaner and I dont have the air gap intake...
what kind of carb is under that air cleaner.. I have an edelbrock and only a mild drop base will fit.

When WOT the linkage would touch, grinded out about 1/8" to allow WOT.

I measured the top of the air cleaner to the drain rails of the fenders. Stock measure @ 56mm (2.2") and ZZ383 measured at 76mm(3") with a 1" clearence at stock it should be very close. My original measurements of clearence seem to be off. I'm just happy with one less item to fix.

Looks good, mine is finally in thanks to great help from fellow forum member Mooser. It fought us every millimetre of the way going in. What starter are you using, as I'd like to go with a mini high tq one as under the dumb heading.
I thought that my old sb had a 153 tooth fw, so just bolted my existing starter up fighting to get around those headers. Turned the key and it just spun. Pulled the old fw out (168, 14") and the auto flex plate (153 12.75") that came with the ZZ383 crate and shook my head at my dumb mistake.

I had to grind a bit off the inside of the valve covers as # 2 and 7 rockers hit. Took the vette for the 30 mi. break in run and oil change. Very happy with how smooth and strong it pulls. Lots of small parts start arriving tmw from C Central to replace some of the 42 yr old worn out ones.
Anything new on your vette?

Its from a 1995 Ford Bronco. You need to cut off a piece at the rad. The stock hose has one more elbow and the diameter is to large, but once you cut off the elbow it fits very well. Its not perfect but it is a stock part.

This is great to know. I am thinking of doing the same with my 383 using an air gap and Holley a double pumper carb. Does anyone know if the clearance is same , more, or less in a 68 SB hood as opposed to yours?

The heads are drilled for both vortec and sbc intakes. Do you have the Air Gap on your current engine, how's the fit?

If I had of known early last week i could of test fitted all 3 hoods that i have, (72 sb base, Lt-1 in storage and L88). I have the L88 hood on and used a drop base for clearance. I went with the Deluxe version which is 450 hp/tq @ 4500 rpm. My previous 383 I had used a Torker intake which is a low rise intake and with a drop base both the sb base hood and Lt-1 fit. I didn't need a drop base to use the L88 hood? The intake that came with the new engine is a few inches higher than the Torker and as previously stated I needed a drop base to fit my L88 hood as the air cleaner lid would hit.
