They all say 327. You don't think they would cast new 350 blocks now do ya ?

what you mean cast new 350 blocks?

is it a 350 or a 327?

S.J.S.

The 350 blocks all say that.

NewbieWar

Then why say 327?

anaik

327 are the last 3 digits of the casting #. Gaze upon this link.

327 on my engine when tranny was out

The differnce between a 327 and a 350 is only in the stroke, they both have a 4 inch bore. By changing the stroke of the motor you get the 350. As far as I know the 327 is the smallest 4" bore motor in the SBC line up. Could be the reason.

The original Z28 (1967) had a 302 with a 4" bore.

No, it is because of the part number. Just like someone else said, it is the last three digits. It is like 10830327 or something like that. I have had two lt1s and they both said 327.

got_hp?

aahhhhhhhhhh.............get rid of that fram filter!


btw, wth is up with your driver side exhaust......whats that big can shaped thing?

jasons93z

i was thinking the same thing

rlax31

it's always been like that since I baught it. It's a 97, so I just thought it was the other cat, but I'm not sure. Doesn't matter, I'll have headers/y-pipe in a few months (finger's crossed)

97Z-M6

its called a dual cat system. thats the first one.

You have heard of the dual cats on 95-97 LT1's? That can is the driver's side cat. The passenger side of the exhaust has the cat in the usual place, under the passenger side floor. Check out my photos in my sig to see how screwed up the headers look for a 96 Z28 when you have to retain emissions.
