Thread: Help Identify engine

I 'm trying to ID a SBC

The block cast# on the left rear GM 355909

The stamped # on the right front is 5719

I'm trying to find out what I have so I can get correct Tune-up parts and specs

plugs
wires
dist cap

Can anybody help?

355909 appears to be a 1976-85 305 c.i. small block.

The early blocks have the dipstick on the drivers side. The newer models, from 1978 on, had the dipstick on the passengers side.

There is also a listing for a 355909 262 c.i. motor that was in the 1975 and 1976 Monza and Nova.

Dipstick is on drivers side therefore I should assume its a 76-77 305?

What does the 5710 denote?

It's a little known fact that if you Google a Chevy block number, you'll get mucho information. Most of these block codes are on the web.

355909 = 305 76-79 Truck
355909 = 305 78-79 Pass,Camaro,Malibu,Monte Carlo,Nova

This same casting number was used on a 1976, 262 C.I. block.

I'm pretty sure that 355909 ended with the 1979 year, and was not used into the 80's - but I could be wrong.

This is a great site:
