350 4 bolt SBC

**HK1837** · 04-12-2013, 08:38 PM

Just picked up a STD bore 3932386 4-bolt short motor locally for $300. Some rust scale in one bore where a rat p!ssed in it or it had water sitting, but if it needs a sleeve so the whole thing can go 0.030" so be it. When I saw the photos and the cast number (so saw it was a 4-bolt, Flint 1968 cast and 3932386) I hoped it might be a high performance engine out of a 1968 or 1969 Z/28 or a 350hp 350 Corvette engine. But alas it is a 1969 K10-K25 manual truck bottom end. Same same, heavy duty application, just WN suffix on the assembly plant code rather than MO, MP etc. Still a good one to have. Only difference would have been heads and cam, same crank, rods, pistons.

I hope you're telling us this because you want to sell it

Geeeeez! The block is worth that! Let alone the rest of the motor. That would be a forged crank then too wouldn't it?

Good buy mate.

I thought it might have been a forged crank too, but it is a nodular cast iron crank. I just grabbed it just in case I have to build another motor for the HK GTS i'm working on. I have a complete 350 that came out of a HQ coupe for it but it is an unknown, worked good 5 years ago but you never know when they sit.

No such thing as too many spare 350's anyway. Like money in the bank.

I may even turn it into a 327 as I have a type 2 HK GTS327 short in the shed that has +0.030" pistons in it after a recent rebuild before I got it, so just linish the crank and put new rings and bearings with that rotating assembly in this block. It'll depend on the old early 60's Fuellies at my mates place, dunno if they are 461 or 462. 461 will be too high in compression with 350 flat tops, but are fine with a 327 (around 10:1).
