Is a True 1968 z 302 a large Journal ?
 
Ok I have stumbled across 2 302s which I know are pretty rare and hard to find and the guy who I found them from is giving me one for free, I want to use just the block and build it to a 383, I know the 302 is a 327 block with a 283 crank but my question is, Is it a Large journal ?. Can I use this block to be a 383 ? thanks

by the way the codes were Block 3914678 and I could not find the heads true identity but the code is 3917298 thanks cya later

If it is a real one (which it is probably not) sell that stuff on ebay and get about 5,000 for it.

according to mortec the casting number is right....go ahead and hack it up.....lol

chevy350_Camd 05-22-2008 02:05 PM

Yeah
 
I know I could get alot of money for it, Do you think it would honesty sell that High ?. I kinda wanted it for a block but If it can sell that high well I could get more than just a block lol

The 302 for 1967 was a small journal crank. They made only 602 of these units. The crank is identified by a wide V notch on the flywheel flange. The 68 and 69 302's used the large journal crank. cast #3941178 (Late) and 3279 (early), also ID'd by the V notch. If the notch is not there, it's not a 302 crank. The block casting you have was also used for the 67 large journal 327 and 350. I would look everything over good for the casting DATES as well as numbers, and find out just exactly what you have before you ruin good vintage parts for a 383. 350 blocks are a dime a dozen.

Like stated before they only made 602 of these, so the odds of you having one is about one in a billion. However if you got that lucky and the guy doesn't know what he has that is his problem.

You would definately have the only one on ebay so I think you would generate a lot of interest and the bidding would drive the price way up there.

Cool
 
I got 2 lol According to you guys it does have a v notch the casting numbers say it is and the guy says they are

chevy350_Camd 05-22-2008 02:23 PM

Well
 
Do you think I should put it on Ebay ? Can anyone tell me what the heads are ?

If they are true 302 engines you need to speak with your parents about what to do I see your age as 15 in your profile.These are worth quite a bit of money to the right people, perhaps enough to put you well on your way to a college education.As stated before 350 blocks are a dime a dozen don't ruin a period correct extremely rare engine for a run of the mill 383.Friend of mine had one in a truck he bought and it was purchased by someone in La. for I think $4000.00 sight unseen, the gentleman even sent a semi after it. He didn't even care if it ran just that all the parts were there.

Before I would believe its a 302 and some fool is giving them away, I would want to see the suffix code. It is located on the front passengers deck on the block. Give us the code and we will tell you what you have.

chevy350_Camd 05-22-2008 03:17 PM

Ok
 
It will be in a little I got to work kk Ill tell u and by the way the heads are 3917293 not 3917298

Those are low-perf 307/327 heads.

Do you have any pictures of the one you got? Crank pictures? Only 302 i've ever seen was a good buddy had a correct, numbers matching Z28 302 back in high school. Gray/silver with black stripes, 4 speed, awesome car!

chevy350_Camd 05-22-2008 03:44 PM

Ok
 
This is the suffix code v1030wy

chevy350_Camd 05-22-2008 03:46 PM

302 ?
 
Well it would be nice knowing what it is but I think I might win either way, lol one possible way is I hvae a true 302 and the other possible way is I get to put my motor back together with the block if its not a 302
