​​​​​​​it also has steel crank hardened and cross drilled with twin tower heads. To hear its a 22bbl truck motor is to say the least disappointing. Can you tell me where that info came from?QUOTE=JohnZ;1596619345]1958 Flint 283/160hp 2-barrel manual transmission truck engine, built January 23. [/QUOTE]

From the "Lime Book", the most authoritative source I'm aware of for decoding Chevrolet V-8 identification markings.

The Lime Book, and the associated Lemon Book, have both been out of print for a while.

I keep telling myself that I will resume printing one day, but that day never seems to come.

Stay tuned...I have another idea.

Entire engine code is 3737739, date code is A178, has a steel nitrided and crossdrilled crank #3735236 , and x58 twin tower heads. I can't believe it started life as a 2 bbl

That engine got those heavy duty parts because it was a big truck engine. Not your basic pickup truck engine.

They didn't use x58 heads on 2 bbl vehicles and I still can't find a "P" suffix.also the 739 code used on trucks is not the 3737739 code. So much for just using last three digits.

Get notified of new replies

To suffix code

A good friend bought a nice '59 over 20 years ago. It had a 400 small block in it at the time and ran extremely well. Shortly after buying it, he decided to remove the 400 and replace it with a correct 283. It took him over 6 months to find a 283 block that was suitable for rebuilding even back then. He actually bought 3 blocks before finding one that was worth rebuilding.

I personally would much prefer a 283 from a truck suitable for rebuilding over one that needs major machine work or even resleeving. Needless to say, good 283's are becoming very scarce.

Good luck... GUSTO

I think all small block crankshafts of the era were forged and received one of two surface hardening treatments. Nitride or tuftried.
Are you sure the mains are cross drilled? Is the hole straight through each main journal?

No, not straight through and as i recall not every main. Curiouser and Curiouser? And again on the suffix "P", I can't find a p code by itself and they don't occur till years later.
