Question about a 1964 chevy chevelle malibu

Hi, i just got a 1964 chevy malibu 4dr sedan with a inline 6 and i was wondering what the ci's are and the hp, thanks for any info.

Ah, yes the $2500 Chevelle.

There were 3 six cyl engines offered in that car:

-194 cid, 120 hp@4400 rpm, 177 ft. lbs @2400 rpm
-230 cid 140....@4400....... 220..........@1600
-230 cid 155....@4400....... 215..........@2000

Externally they looked pretty much the same. They all had the same piston stroke, the 194 had a 3.565 inch piston bore. The 230 had a 3.875 bore

The two 230 engines used a different camshaft to get the different power specs. I am not sure if the valves themselves were different.

My guess is that if you have an automatic transmission, it will have the 155 hp version. A standard transmission car probably has the lower powered 230, but might have the 194.

The late L6 are 250 cubic inch and use a different head. The trick set up is to get the later block and use the early head with small block valves. The later blocks came with HEI dist.
