Hey there everyone! New member here to the group. I have a question about my recent "68" purchase that came with a SBC and 4 speed Sag. I was told by the seller the block installed is a 350 and it is the original block equipped on this car. Not sure how true this is. No heads on the engine just the short block. Casting numbers are..
#F1014HF (pass side pad stamping)
#3858174 (Rear left side casting)
Online decoding charts give me both, a 327 and 350 for F1014HF stamping and 3858174 casting there is blogs about this being a mystery block possibly a 327 or 350 out of some corvettes. Is there any other indications on the block I can use to decipher? I'd like to keep this block and rebuild it if possible especially if its matching numbers. Any help is greatly appreciated.
-
Casting number and HF application code indicate a 327. Either from a 65 or 66 full size Chevrolet.

Welcome to the site. Post some pics of your new purchase (please)
:)
-
I think your car would have to be an SS to have a 350.
-
Thanks for the info. Here are some pics of the first day I brought it home.
-
So that sums it up better. I suspected the block was not matching for 68. Could the block possibly have came out a Corvette?
-
Great pics. What are your plans for it? Stock colors per the trim tag, or a different color in mind? Wheels?
-
Thank you. Stock Tag color is Teal Blue with Black standard interior, 4 speed trans and V8. I think I will go either Teal blue or custom Black with the louver hood and RS grille. Havent decided what engine most likely will start with a Gen1 small block and with a M20 Wide Ratio. Later will look into going LS. Already has a 12 bolt posi not sure if original but I am definitely content with keeping that! On the wheels I love the gunmetal American Racing Torque thrust wheels on 15 BFG's...Just never get old for me. Im more of an old skool guy :o 8)

No the block is from a full size car like an Impala.
What is code stamped on the front edge of the passenger side axle tube? And how does it compare date-wise to the build week on the trim tag on the firewall?
-
If it has a factory 12 bolt, (dates line up), would that indicate it may have been a factory SS?
Could you get a LM1 or plain jane car with a 12 bolt, and not have an SS, Z, Dealer super car?
(Sorry 68 guys, I am not well versed)
-
It's OK Austin. Yes, an original 12 bolt in a 68 is a good sign of an SS or Z28. The L30/M20 combo also got a 12 bolt. There wasn't an LM1 option in 68.
In 67, there were even some 6 cylinder cars that got 12 bolts. They were installed when the 10 bolt ratio was not available or a heavy duty axle was ordered. I personally know of 2 cars that were that way.
Fixed typo

If it's a 327, slap a 283 crank in it and wind 'er up!
-
But don't forget to change pistons as well! ;D
-
The old 301 was a 283 bored out to 4 inches.
There is more to making a legitimate 302 than a 327 block and a 283 crank. A properly build 327 will rev almost as good as a 283 or 302. And if both (327 and 302) have similar compression, same cam, similar ported heads, and good rods - which do you think would be faster? :)
-
No replacement for displacement.

I agree with Bryon's notes about that more is required than the crank... and that the 327 engine is a good engine -one of the best chevy ever built for balance between power and torque. They certainly have better torque characteristics than the 302 (due to it's longer stroke), but all things equal .. don't forget that 'almost' inserted.. :) ie. the 327 would 'break - throw rods thru the side of the block'.. before it would rev as high as a 302 (simple mechanical loads problem).
And.. don't forget that 302/Z28 beat a lot of 327, 350, and even big blocks at the drags for years... :) (No, not always... but often)... :)
PS. And don't forget the sound of a super high revving 302~~ Some of us might rather 'lose' a drag race in a 302 than win with one of those big old lunky BBs.. :)

That sounds like someone with a Z would say.. Who needs super high RPMs when you have torque?

Me!!
