I'm running a Eagle stroker crank with Scat 6.125" rods and Diamond forged pistons with no problems for more than a year.It revs past 7000rpm with ease.So it's plenty strong and priced right.

 

Any ideas on if I can use the stock rods pistons and just pop in the 4" crank. Im trying to get out cheap and still have something that can handle n20 and 700 crank hp plan on shifting around 6300

 

I don't really think that stock rods and pistons are up to that much power. Forged pistons will allow you to spray more but I would get a complete assy if possible.

 

There's no way can you use the stock rods or pistons.The pin location and thus the deck heights on the pistons is wrong for a 4"stroke crank.And aftermarket pistons are designed for use with longer 6.125" rods.

good find

 

Good find but its jsut part of the equation you would get a better deal buying the full rotating assembly.

 

When You're Looking For 4l60 Performance Parts Stay Away From Any Of The Stuff Made By Torque Drive. It's Sold By A Place Called Performance Automotive And Transmission Centers Or Under The Raptor Name. The Stock Parts Are Stronger. 600 Miles And They Failed, And They Wont Stand Behind The Warranty.

 

thanks for the input Ill look out for em, Ive heard of raptor before
