What makes a 355?
« on: December 14, 2007, 02:57:49 pm »
I saw in someones project post that they had a Vortec 355.  What's that?  I have a Vortec 350 in my 76 Chevy, but I'm curious as to what a 355 is.

Thanks,

T.J.

355 = 350 + 0.030 overbore.

Oh, I gotcha.  I've never heard it called that before.  I almost thought 355 was refering to the OLDS engine, but I realized that was a 455.

Thanks
