305 or 350

how do i tell its a 305 or a 350 did a 74 nova evern come with a 305

Had a 74 with a tre fitty fo speed

was a nice nova

I dont think 305's had quite made it to the scene yet

i agree i dont think 305's were around... but who knows maybe nova 75_77 will say something :D:rolleyes::p


EDIT: wiki says 305s werent in novas until '76

The 305 was not released until 76 so you either have a 307 or a 350. Do you know if the engine in there is the original?

I thought 307 stopped in 73?:confused:

I think you are right, sorry about that:o

Here is what I found. Sorry for the wrong info...

307
Production: 1968–1973
Displacement: 307 in³ (5.0 L)
Power: 115–200 hp (86–149 kW)
Bore and Stroke: 3.875" x 3.25"

if its original...its a 350

To my knowledge there is no way to tell the difference between a 307 and a 350 unless you run the casting number and/or suffix code.
...not sure about 305's though

Casting number is on the driver side of the transmission mounting flange. Suffix code is on the passenger side pad in front of the surface where the head mates with the block, just behind the alternator.

There are a bunch of sites you can decode the numbers at...or just google the number along with "small block"

I had to run the numbers to show the owner that the 73 Nova Custom I was buying was a 307 and not a 350

like said above, 305 was not available, However, that does mean some one did not put one in there:D


you need casting numbers and the casting date off the back of the block. the casting date will look something like

b 25 9

Which translates to February 25 1969 or 1979 or 1989 or 1959 or 1999

im alittle late but yes i knew the 305 answer. it wasnt in novas till 76 but my 75 has one in it that the previous owner swapped with the 262:D

oh and also the 262 has the same casting number as the 305. (in some cases)
