i am buying rods for my engine. which size do i get/need? are the eagle 6.125" rods better than the 6.1". i was thinking of getting the 6.1" but i see that everyone uses the 6.125", why? wouldnt the 6.1 have less rod angle and put less stress on the piston? any info would be appreciated.

 

Are you building a stroker?

 

yes..408ci

 

ya, whats the bore x stroke your working with and have you chosen pistons yet?

on a 346 it usually goes

6.098 - 6.1 rods with pistons w/ a ~1.340 CH (stock)
6.125 rods with pistons w/ a ~1.315 CH

generally you want to keep things within the deck height.

 

.030 over 6.0 with a 4 inch stroke use 6.125 rods

 

no pistons yet, bore 4.040x stroke 4.00..which rods work best?...

 

do they make off the shelf stock length rods for a 4" stroke? all i've seen are pistons setup for 6.125 rods w/ a ~1.105 CH

 

F.I.I.K..

 

lol, i hope you arent putting this motor together.

 

actually a friend of mine is, i am just gathering the parts. and yes he is well qualified since he works at a very reputable speed shop in houston. i was gonna give it a shot..i had my glue gun and duct tape ready in case i broke anything, but after he offered, i couldnt turn him down
