1  Camaro Research Group Discussion / General Discussion / Re: your going the wrong way! 3.31 gears in a 302 powered 69? on: Today at 03:42:03 PM
Here's what I meant by that comment.  Sorry I should have explained better.  For some reason I thought the OP had standard 3.73's, that keeps ringing in my head.

3.31 x 2.52 = 8.34
3.31 x 1.88 = 6.22
3.31 x 1.46 = 4.83
3.31 x 1      = 3.31

3.73 x 2.20 = 8.20
3.73 x 1.64 = 6.11
3.73 x 1.28 = 4.77
3.73 x 1      = 3.73

That seems clear to me....  M20 with 3.31:1 has better gearing thru 1-2-3 gears than M21/M22 with 3.73:1 rear...  AND you get a better highway gear (10% better mileage at 10% less wear on your engine)...  Smiley

Smiley   at 86, if we live that long, I doubt any of us will spend much time looking forward to our next drive and 'power shifting'... Smiley

The options, and the cars themselves, seem 'cheap' nowadays, but back then.. most of the buyers for muscle cars and performance cars were young men, and $3000 was a lot of money!   When you're struggling just to get a down payment for the car, then a few hundred $$ for what today seems like 'have to have options'... were considered 'unnecessary!   Smiley   Heavily options Z28's and the like were in the minority and pretty rare when the cars were new.. Smiley   stripped down models were the mean!

Loved it. Dude was redlining the crap out of that baby!!

Maybe on a 'test drive'??  Smiley

We are all very sorry for your loss, Jeff!

On the positive side, he lived a good long life.. even enjoyed ownership of a Camaro convertible when it was new, and for you to have that car now... provides you some fantastic memories.. and on top of that?  TO have that photograph with him in it after restoration!~   Many of us would give much to have similar...  Smiley

Everyone says you don't want 3.31 or 3.55 gears in a Z - too hard to launch. You never hear that with a LT1.
It performs about the same as the 302, but with more torque on the low-end.
In 1970, the Trans-Am series allowed for destroking motors. So Chevrolet went with the LT1 in production and TA teams destroked it back to a 302 for the track.

If you want originality, it needs a 302. If you want a driver and more torque across the spectrum, then a stroked 302. Y'all remember the Z29 feature car?

Obviously, this is heresy to some. Smiley

and I have no argument with Kurt's comments either, except for this one.... that's a big word.. ''about''...  Smiley

"It performs about the same as the 302,"...

I prefer a 350 for everyday driving.. I've even *considered* installing an LT1 crank/pistons in my 302 block...  but.. even the 1970 LT1 engine didn't rev as quickly or as high as a well built 302...  If I'd put a 350 crank in the 302..    the end result would be .. 'The THRILL IS GONE!"...  Smiley

I don't recall reading or hearing that anywhere (not that it means anything!)...  Where did you hear or read about that Dave?  ie.   the source for the information?  I'd love to read it myself...

I have a 71 low compression 402 (date matched heads/block) I cant give away up here. Maybe a regional thing , but  pretty unpopular engine on the North Coast ? Although a 396... 2 camps tend to be your high r  small blocks , or 454+ cubes, "427"s tend to be stroked 400's up to 454's(with some issues)

302's have a unique, wonderful sound throughout the RPM range ,they just do. But....they are not real traffic friendly, they were purpose built ( Kurt S.)

My 400 (sbc) backed by a turbo 350 and 4.88's pulled the wheels ,ran consistent 12.5's (fast for a street car in the day)and behaved well in traffic. Did I mention shift point was 7800? Never broke with that set up. Although looking back, geared to steep, was a better 1/8th mile car.

Yes the 302 is going back in the Z, ready on the stand.

Dollar for dollar, cant go wrong with a crate 383. but...

IF it is a Z ,it needs a 302 (smiles) They define each other.

I agree with all your points, Jano..  except ONE!   you CAN give that '71 402 away..  to me..  and I'll come pick it up!  Smiley   I need a 'torque motor' for the '72 El Camino I'm building.. Smiley

Hey Rob, welcome to CRG.  You've come to the right spot.  Tons of knowledge here and you'll soon see just how special these 1st gens really are.  As far as building a 302,  Yeah it'll scream but why not just rebuild the 402 (essentially a 396) big block that you already have into an even more screamer ?   Regardless.. have fun and enjoy !   Smiley

If you've never heard a 302 at above 8 grand (I've had them that would turn over 10,000), then you haven't heard a V8 'scream'!~  Smiley       A 396/402 is 'groaning' at 6500.. and I can't imagine one screaming... Smiley    

Of course, if stump-pulling torque is your thing, then the 396/402 will do it for you!

Gary your absolutely correct.. Guess I should of worded it different.  A 302 is definitely the screamer by far!  I was thinking more in the line of HP and a much more powerful engine in a mild state of tune and could even get a little mpg.

Smiley.. I knew what you meant, Darrell..  but one of my roles here is to defend the reputations of the 'little guy'.. (302).. Smiley
Or..  as once proclaimed by one or more car mags... 'The Mouse that ROARS'.. Smiley

Manual was more prevalent on the high po cars from my observations. 

Absolutely...  PS and it's pump robbed horsepower...  PB was considered OK.. but not PS on a HP car!  Smiley

I wouldn't put a 302 in anything by choice. Realize several of the TA teams reputedly cheated and ran stroked 302's (aka LT1 350's).
The *only* reason Chevrolet made the 302 is because of TA rules. When the rules allowed it, Chevy went to the LT1.
A little balancing and you'll have more power and same rpm....

Does that sound a bit like '302 envy'HuhHuh   Smiley  Smiley

Thanks, December narrows it down for me.  These December cars are a pain, right when alot of changes happened it appears.
    Probably safe to assume a 4th week of Dec Norwood car would have YH's on it.   Oddly I just did a search and the only thread that pops up on AD wheels is the one we are talking in, lol,  but I'm not computer savy either.

I updated my prior post with another link which might help.

Re your 'December car' being a pain re the changes... OR you could have a LATE '69 car when many of the parts were being changed to '70 model year production.. Smiley     'running changes' are a fact of life in manufacturing whether it's a '69 Camaro, other car, or whatever...  It adds a lot of fun to our searches for information and parts though..   Right?  Smiley

I seem to remember a discussion that mi- December is the time of the last ADs, or when the switch happened.  I think this is the link I recall:
http://www.camaros.org/forum/index.php?topic=7767.msg54018#msg54018

I had a 'Y 1 8 10 24 AD' wheel which was one of the delivered wheels on a friend's '69 Z28 that he bought off the lot in Dec '68 (I don't have the VIN of his car so I don't know when it was built).  I've also seen references to YH wheels with a date of 17 Dec...  Maybe someone else has more or better information.

I think the 15" FW wheels are a close match. I have seen sets for about 200. If you continue to scout around you could gather other parts that look or perform similar to the original Z stuff and have a fun car.

I've bought 15x7 FW wheels in pairs for as little $20-25 each at swap meets the past couple of years...  you just have to look and scrounge.. Smiley   ($40-50 each is probably closer to the 'market price' - what most people ask for them as bare wheels).

Here is a link from past CRG discussions which itemizes the exact differences between YH and FW wheels.
