On left hand menu - Photos of my... you can see one picture of my L-88 Hood mod in my 1973 BB

 

I have more detailed photos on my laptop if somebody need more pics (sorry not on any server) so hit me with a email and i can send reply with pics...

 

Very nice looking vette.

 

yes i see it,, now i understand how it seals to the chrome rubber ring on the carb ,,when you installed the air chamber,does it work toghter with the origional coul on your air intake,or did you have to change that?

 

Well - my poor english skills - if I understand what you actually ask by
"origional coul on your air intake" - well I do not understand

But let me explain: I have stock L-88 intake manifold over my BB engine and on top of that is a stock Holley 850dp without spacers. I used to have a crome (very cheap) Taiwan boys aftermarket air cleaner with 3" paper element. From that aftermarket system I only left the drop base to my existing set up. I clued the black seal on it. The seal just happens to be so high that when I close the Hood it firmly seals the airbox and the drop base - NO hot air enters the carb. Then about the hood - it used to be a aftermarket long L-88 Hood without the airbox - but when doing this mod I bought the box and "clued" it in below the Hood. The Hood was closed at the rear so I had to saw it open when installing the airbox.
Maybe this explains your question as well?

Also I removed the choke linkage and plate at the same time and put in a K&N stubstack - that leaves slightly less that 2" space between carbs highest point (stubstack nowadays) and the Hood.

 

my mistake when you said 73 bb i was thinking you had the same hood i do on my 73 ,,,forgetting you have a L-88 hood(which has no cowl door) i guess i should of said ''do i still use the cowl door with the instalation of the L-88 air box-(will i still have that flapper w/the L-88 air box or will i remove it)

 

Yank the flapper, I did, it is an air restriction, wish they would have molded the cowl section a little better to allow more air flow on our 73's.

 

Well.... now don't laugh guys but I was thinking more on the lines of using a C-5 air intake, turn it over and mount it under the core support. Then fab some hose up to the dual snokel air cleaner. That would give a guy plenty of fresh air with the vacuum effect. It's a nice thin but wide plastic air intake. May not look bad. Just an idea.

 

I don't think the L88 air box will work with our stock '73 hoods. Likely only fits and works with an L88 hood. I say this because the scoop (hood bulge) height on our '73 hoods is nowhere near as high as the L88 spec... I don't see how the air box would seal at the top of our hood when you try to glass it in - unless you trim it and add glass down the sides to get it attached...thereby lowering the base of the air box likely to the point that it may only allow the hood to close on a stock or low-rise intake manifold and carb combination - if that... I would look for an aftermarket L88-style hood (long for '73 and up with no wiper door) and the air box. Then you slip an air filter up in there, resting inside the hood. The base of the air box is what rests against your foam seal and the air filter base. You attach a small diameter spark arrestor like most cars would take the air cleaner lid - screwed down on the carb. A very neat system!

 

i like it heck!!!! i gotta buy a hood l-88 air intake sounds like alotta doe!

 

heres what i did. mine is very simialar to gs3's but made from sheet aluminum, tig welded together. cut a cardboard template for the bottom peice that will be under the carb. on my 78 i had to make room for the wiper wires and part of the air cond, box. after you make a template cut out the aluminum for this piece and cut out the center hole for carb clearance and one for dist. and pop rivet to a chrome air cleaner base. now install the bottom base as you would a normal air cleaner with the new piece attached. now use playdoh or marsmellows as depth gauges. place playdoh on the new base in several areas and close hood. open hood and measure playdoh height. subtract 1/4 or 1/2 inch from this for the foam or rubber seal and you have the height measurment for the side piece. i bent the radius for the round front part on a tree and cut the extra off flush with the ebds of the base piece. now make a back piece and tig all of this mess together. i used 1x1 foam from a window sealing manufacture ( king something or other ?) and cut a groove into 1 side of it with a cutting wheel grinder, so you can place on top of the side piece to seal to hood. now put the chrome air cleaner lid where it would normally be. ideally you would use the one thats open on the top too from k&n. i originally used rubber hose to keep the wires being cut at dist. hole. now have the rubber covers made by ford speciffically for a dist. later c-3's did not have the flapper or were open to the wiper area. with a dremmel tool it takes 2 minutes to open your hood to this area by cutting out the vertical part of the brace, leaving the horizontal part for hood strength. you now have a hole open to the wiper area about 13 " long and 3 " tall.
