Hi everybody.  I am new to this forum, 1st day.  I could sure use some help on this mess I'm in.

I took the carburetor off a friends 70 convertible and found that the thick gasket had burned through.  Although I can't prove it, I suspect that this gasket was professionaly replaced about 3000 miles ago.  We have ordered a new gasket and new heat sheild but I'm concerned that it will just burn again.  In fiddling around online, I have discovered that the intake manifold, casting number 3927184, seems to have been intended for a 300 hp motor (the sticker on the air cleaner says 350 hp) and the carb, p/n 7043200 was made in '73.  So now, my questions are these.  Is this carb suitable for this intake?  Is this a 300 hp or 350 hp motor?  Is there something else I should fix to prevent burning the next gasket?
 
The engine number matches the VIN but it doesn't seem to help me determine how much horsepower this thing is supposed to make.  Any ideas there?

To the right of the vin on the stamped pad should be a code that starts with a letter V followed by the month and day of manufacture and ending with a three letter suffix code.  Look up suffix code here.  I recently learned this myself, so to help out a fellow newbie.

Yup, after I posted my questions I read a little further.  I new about the codes but I couldn't find them on the block.  didn't occur to me to check the "v" number.  Thanks though.

The suffix numbers agree with the Corvette Black Book, so hopefully you are all set.
 
And welcome to the site Nathan.

Ok, it's a 350 hp motor, thanks everyone.
 
I also think I have figured out the intake casting it is supposed to have and even the carb model that it should have.  Does anyone have a good website to buy them from?  I have searched for hours and can't find a price or even the parts at all.
 
thanks again

The carb and intake for a '70 350/350 is gonna be hard to find, but not impossible. Get out your friends wallet, I bought a correct carb in a basket for $400, and I am waiting on parts for it. My intake is correct. Remanufactured carbs for the L-46 pop up on EBay from time to time for about $1000.

Tell your friend congrats; '70 was the last year for the 350/350hp option.  Q-Jet is a 7040207 or 7040507 depnding upon emissions equipment; intake is 3965577 cast iron.

Becareful as I had  a horrible experience with Chicago Corvette when
buying a correct numbered carb. Most of them are junk and hardly worth
trying to salvage. Avoid CHICAGO CORVETTE when buying anything as they are not honest!!!!!! Contact me for a good source and quality rebuilder.

Hi,
 
I saw your post, and I also have a '71 LS5 with a 4 speed. I am looking for a rebuilt Quadrajet, done right. I've heard a lot of horror stories about the remanufactured jobs at some of the standard suppliers (who shall remain nameless!).
 
Which rebuilder/outfit would you recommend?
 
Also, I would need a tach drive distributor, does not need to be #'s matching, but in good working order, converted or ready for a conversion to electronic.
 
Thanks and cheers!
Bally
