3931063 is the casting number of a cylinder head, not an engine VIN derivative. The numbers you're looking for will be stamped (not cast) into a small rectangular surface on the engine block in front of and below the passenger side cylinder head.i

20 more HP would be almost a 10% increase. No aftermarket intake can do that. I'd expect more in the area of 2-5HP increase. Buy the intake for looks, not performance.

No matter how highly modified a street engine might be, an aftermarket ignition system has no advantage over the stock GM HEI. There is no connection between the 'strength' of a spark and the power the engine creates. Either the spark ignites the air fuel mixture, or it doesn't. There's no...

It's also true. Why buy junk?

What failed last time was poor quality aftermarket junk- which you replaced with more poor quality aftermarket junk. Throw it all away and use OEM GM stuff.

The original GM unit is the best quality and performance. What's wrong with yours?

I think you'll find similar events on any discussion board- if you start digging.

I think the entire site is very well moderated. Keeping in mind that the entire purpose of the internet is sharing pictures of kitties and arguing with strangers (and sometimes simultaneously) it's almost impossible to consistently get the moderation part of it perfect. I can think of at least...

The car weighs about 3500 pounds. A typical battery weighs about 40 lbs or just over 1/100th of the total vehicle weight. Placing it one side or the other of the centre of the car would make little practical difference.

You're right. In digging through my notes, I've found that not only is the stock 3/4" bar no longer available, but the 7/8" bars are long gone also. Lack of demand apparently.

I thought the stock size was 15/16".

All Corvettes from '75 onwards came from the factory equipped with HEI. The previous owner of yours downgraded it with a hokey aftermarket unit.

'73's don't have a glass filter, most are a fire hazard so I'd get rid of it. As you why you've got water in the tank, this can only happen if the rubber surround drain gets blocked. Since you've removed that, are you sure there's not some nasty kids in your 'hood? Drain the gas and refill...

That looks like an aftermarket rotor. I've not been impressed with the quality of many pieces I've seen over the years. Since this component and the cap do not contribute to performance, I'd stick with OEM stuff.

Sounds like the guy on CF is confused. Obviously this website is not a store of any type, it's an enthusiasts forum like CF itself but much nicer. ;)

Not sure why the Corvette Forum guys sent you this way for help Removing RPO Code Label from Glove Box Door - CorvetteForum - Chevrolet Corvette Forum Discussion but welcome!

Where is that covered under the warranty or lemon law legislation?

You are. Are all these features on the same fuse?

Google doesn't seem to know anything about it take this piece of crap away and replace it law - Google Search :chuckle

If you're thinking of the lemon law, it won't apply as yet.
