That one ... I would have NO idea about.

That new Eagle crank they are talking about in Internal Engine is sounding good to me though. That and some forged rods maybe, along with some nice low compression pistons. Maybe in the near future some cheaper rods will come out too to make engine building more affordable.

 

Are you planning to build a stroker? If not, I'd say that stock crank could hold 650rwhp+. I'd jst be scared about the rods and get a set of H beams

 

I would like to build something with some more cubes. I like to do a bore and stroke, but I don't know how the funds will hold out for that one.

I need a job to do all this of course, and the narrow job market here in East TX is tough to start with, being young without a BSA and 3-5 years exp makes it worse .... Maybe after the first of the year though.

But yea .. I'd like to get a 6.0 and bore it and stroke it. Maybe 400 or so cubes? I dunno .. Can you bore a 6.0 block out to 4.125? If so, that and a 4" crank would make 428! Could you imagine a blown 428 LS1?!

 

Or ... a 6.0 with just a 4" crank would make a 402.

 

 

That chart is WRONG.......the 4.8, 5.7, and 6.0 ALL use the 6.098" connecting rod....that was what we were discussing about 10 posts up the thread

 

The link you posted is full of mistakes..

Here are my sources:
John Juriga, GM Powertrain Assistant Chief Engineer for Gen III Passenger Car Engines... "The sintered, forged and shotpeened, PF1159M steel, 6.1-inch connecting rod introduced in 1997 carries over to the LS6. Beginning in MY01, all Gen III rod cap screws are stronger through a change in manufacturing process used to heat-treat and roll the screw’s threads. This particular change came as a result of the LS1’s use in the American Speed Association (ASA) race series during 1999". http://www.idavette.net/hib/ls6/page3.htm

Manley Performance: A company that makes many aftermarket parts for the LS1/LS6 said this regarding their own connecting rods, "The rods come with a 6.125" center-to-center length and large style (2.225") crank journal size. They are .025" longer than stock LS1 rods, and designed to be used with aftermarket pistons (which must also accommodate lightweight .9281" diameter wrist pins; stock LS1 wrist pin bore is .945")". You do the math.. http://www.electronic-pr.com/pr/MP_H_BeamRods.html

I can find more if need be.

 

then why are the part numbers the same for the 5.3 5.7 and 6.0 rods from GM ?????

 

My bad, I see what you are saying now.. The info regarding the rod length appears to be wrong in your link as well as the chart I posted.. I'm going to hunt that down.. Sorry if I've spread any misinformation.. I'm under the impression the 5.7 and 6.0 are 6.100"..

 

Yes .. please find the truth to this. I was wondering too. If they are infact the longer rods in the 5.3 it wouldn't worry me near as much if I were going to try and spin my motor up to 6500.
