My dad has a engine in his truck. The casting is #3932386 the casting date looks like A 9 or A 6. Looking through mirror while in truck. The code on front is VI0I9HH. The 1's are capitol letter i's. The info shows this to be a 69 engine but the code on the engine shows it to be a 66/67 corvette engine 327. Also this is a 4 bolt block. ????

3932386 1969 327 2 ?? Unverified
3932386 1969 350 300/350 4 Passenger/Chevelle/Chevey II/Corvette/Camaro

HH 1965 327 365 4 s h/p, m/t
HH 1966 327 300 4 air inj. reactor
HH 1969 350 300 4 tur 400

Sounds like a 4" bore block that can be a 302, 327, or a 350. Can be a 2 or 4-bolt block. Large Journal.

Most likely it is the 1969 300 HP 350.

Thank you. Was not able to find that HH code for 69.
