327 rods in a 3.4?

[grandsport3.4]

Is it possible to put 327 small jornal rods in my 3.4 and also does itchange the displacment?

[bszopi]

Yes, you can, although you have to narrow the big end in order to fit 2 on a journal. If you keep the same length rods (5.7"), then no, displacement stays the same.

thanks for the help

Rod length doesn't affect displacement anyway..

[bszopi]

You're right. I was thinking stroke with the change in rod length. But the storke will be the same even with a different rod length.

Change in rod length = change in compression ratio.

Is there any advantages to using a Chevy 327 rod in a 3400??

Its the only alternative to getting custom made rods. They can be had for cheap and a 4340 forged rod will be stronger than a stock one. As said before, they will need to be narrowed, and the wrist pin size is different as well.

[torq455]

advantage is ability to find much stronger rods and decent prices.

[kris gtwhat?]

how about the bearings? if the big end has to be machined would i use the 3.4 bearings? or are the oil spouts in a different spot?

[MidnightriderZ24]

before picture and after picture of machining. stock bearings will work.

Exactly Correct... And here is a nice "Reason Why..." sort of article on the broader subject...

If you go this route, have your SBC bearings narrowed also. I got SBC 6" H beam in my 3.4 and that's what we did to the bearing for proper fitment.

Or you have to have the anti-rotation tangs machined into the rods and caps and use the 60* bearings.

Off Topic: Chief, did you end up getting that Crane you were spying?

factory bearings will work. theres a slight offset, but according to my machinist, its not the first time seeing it, and it will not be an issue. ill find out for sure though
