Engin rebuild help
I have a 1999 Trans Am, I spun a rod bearing a while back and am finally looking to rebuild. I was looking at rotating assemblies and settled on a few. The first is a forged 383 from Scoggin dickey

the second is their 383 with the Callies upgrade
http://www.sdparts.com/product/LS6RA...esUpgrade.aspx
My question is, is the Callies upgraded 383 worth the 300 extra dollars? The parts going with the motor aside from the rotating assembly are a MS4, FAST90/90, PRC 5.3L 2.5 heads(i know the heads are some what of a limiting factor) and a 100-150 shot from a TNT F2 kit.
P.S. current mods in sig.

Well I was hoping to make atleast 430-440rwhp with the set up listed above (383 ms4 90/90/and the prc heads) on motor thru the auto, plus the additional 100-150 from the nitrous. As far as future goals, upgrade the heads maybe bigger cam, nothing crazy more nitrous is always a possibility.

with the power you are planning i would not worry about the callies. if you havent bought the heads yet, you could put the extra 300 towards an iron 6.0 and go with a 408. then sell the ls1 block and buy some ls6 or 6.0 heads. either the 383 or 408 will give you some bad *** power.
