Help Choose Which one!!
Help Choose Which one!! Alright guys im about to order a crank. Heres the dilemma. I posted a few days ago asking about crank sizes. And came to the conclusion that i need to stay with a smaller crank. Now i have a choice of a 3.48 crank (stock) or the 3.75 (383). They are only a 50 dollar difference from where im looking. I already have a set of Lunati Pro Mod Billet 6.125 Connecting rods sitting in my garage. So Please help me choose and pick the best one. BTW its going on a Turbo LS6 and hoping to make around 750rwhp.

I would say bigger is better but then I do not claim to know a ton about turbos either. I would think more displacement would get it to build boost sooner and be able to make more power in the end as well.
okay now im confusing myself a lil. if the stock crank measures at 3.622 then what the hell what a 3.75 crank measure out to?? BTW i have a bare block so i need a crank. Its under a grand which is alot less then i thought i was gonna pay.

Its not, im a dumbass. Ive got an LT1 right now and still learning on the LSx. I called and asked and they said it wont fit. thats why i was confused on the crank sizes. Hey Predator im NOT rich lol. Im in E-3 in the NAVY lol. Where can i get my crank micropolished and nitrated at? And if i do it will be good with boost? Thanks.
