Has anyone heard of running 5.565 length rods? The reason I am asking is I bought a motor last year that was supposedly built by MTI and was a supercharged motor. I broke the motor down to refresh it with some new bearings and such and found out that it has the 5.565 Eagle H-beam rods and wondered if anyone has heard of anyone running these length rods or not. The motor also has a Callies Stealth lightweight crank but since whoever put this combo together they had to add quite a bit of weight to get the rod, piston combo to balance out. I am thinking about going with a longer rod and different piston combo since I dont see anyone running this short of a rod but I am asking you guys if there might be a reason why they went with this short of a rod on a 383 LT1 motor. Like I said above this motor was supercharged before but I will be going with a direct port nitrous kit and shooting around a 250-300 shot.

Thanks for any help guys.

It's deja vu...all over again, as Yogi said.

If you need to change pistons for compression ratio or because the bore needs a rebuild, by all means go with 5.7 or maybe 6.0 rods. If the current setup is sound, doesn't leak, and has a reasonable CR, and you are going for the 300 shot, perhaps you might try that before you rebuild, as you said.

Personally I wouldn't get all that concerned about the "400" rod length. The 300 shot would be of more concern to me.
