Your biggest issue at or around 450\500is gonna be ur transmission. And more specifically the input and tc .... As the input tends to shear or break at 1000 tq or close to it .... So at 500 ur really running the risk of eating a tc and input ... Possibly more .... Do homework .... And don't take the first suggestions and run with it .... Get informed and make smart decisions .... Or it will cost ya a ton ...:td:

I am running an upgraded nv4500 with 1 3/8" input shaft and a dual disc south bend clutch. I have built everything to take the abuse, tom woods driveshafts, np205 transfer case and front and rear ends have cro-mo alloy shafts.

Good deal .... Any idea what rods are in your engine .... If I recall .... Somewhere round 500 is topped off for the factory stuff. ... :humm:

i know guys with 900ish hp and stock bottom ends.

I agree I know a few people with around 900hp that have stock bottom ends and one of them has almost 400,000 on the motor. I really don't think I need to worry about any motor internals for the power I am looking at. Side note, sorry I didn't put this in the performance section just getting used to the site didnt know it was there.

No need to worry about your rods they will be just fine, question tho why did you put a 205 t case in?

I am putting the np205 in because I have several of them on hand. They are plenty strong enough as long as i'm not pulling with the truck also they take up less room and my rear driveshaft gets to be almost a foot longer which will help with the angle.

That it will, but if its too long it may need to be a two piece or aluminium

900 with stock rods ??? :humm:... not what i was told by the crew here at DDP .. gonna have to look more into that because if thats the case then hell i'm gonna shoot for at least 600 then .... LOL :rocking:

click the link in the video in my sing ... and remember there stock rods
