Important if you run D-H/S or SA

Someone working in the NHRA Tech Dept. in Ca. has recently allowed the 1968-71 Chrysler 340 cars to legally use the Edelbrock LD340 intake manifold.
Unless you want this to stand, please contact your NHRA Tech officials and the Tech Dept. in Ca. and let them know your opinions.
If they won't be realistic and reverse this, might I suggest that you request your own Edelbrock intake be legalized for your personal combo! But please try and get the LD340 removed first!

I don't know what to tell you about that Mark. All I know is, right now the intake is legal!

It might be hard to find an LD340 that hasn't had some porting or milled out for the TQ. I'm still looking for some 273 iron manifolds in case Billy gets the LD4B removed. I've had better luck finding the LD4B than the old iron units. Since a lot of combos get to run the Edelbrock heads, why not open most combos up to allow a Performer intake as well? At least those can be bought new and not butchered up already. Just my $.01. I can't afford to put in the full $.02.

Thier you go i think the 454 365 should get a edelbrock intake also,the EDL 7561 would much easier to find than the stock 287.

X2 I like your train of thought!

Thought it was the 68-70 combo AVS carb

I guess nothing NHRA tech does surprises me anymore. I see aftermarket alum. heads allowed with hp. lowered not added. Look at engines with 71 hp taken off. Engines with alum. heads and larger carbs that sure as hell was never made. I don't know when it will ever end. NHRA feeds us sh#t and we keep on eating. Rick.

Carter AVS is also spread bore.

A Carter AVS is not a spread bore, I have run this combo in my 68 Cuda since 1978. For a thermoquad to work without a spacer you would have to machine this manifold. Also my car will still fit in G with this combo. Before you worry to much about this combo, which there aren't that many out there, you might want to take a look at the 91 Corvette which holds the G/SA record at 10.54 at 124 or the 73 Pontiac TA - 455 at 306 hp. If you think all this aluminum stuff helps so much (other than weight) then why is the 70 Duster with aluminum heads 2 hp less than with cast iron heads? The AVS 340 combo & the 383 only take a 1 hp hit with aluminum heads & be prepared to spend big $$$$ to make them legal. Wish I could use a Quick fuel carb or a 4 speed auto trans. Didn't powerglide combo's got a 3 speed, why can't I run a 4 speed auto? That would help way more than a manifold. Can someone tell me, what is stock about stock eliminator these days. Just sayin.
