I'm building a forged 385, wiseco pistons 28cc dish, eagle Hbeams, eagle 4340 crank. Compression should be around 9.5:1. I'm running a vortech s-trim at 8-10psi IC, pump gas. After 500mi break in, I plan on putting a 100 wet shot.

Machine work is done, now I need to decide on piston rings. I picked up a set of Total seal CR3690-45. Spoke to Tech over there and he said I should get the stainless top ring kit, which is like $400 and overkill I believe. They have a CT3690-45 TNT kit, with a ductile iron top ring (mine is moly which I have read about flaking so I'm not going to use it), the 2nd and oil rings are the same I believe.

For my application, would the TNT top be ok, or is there something else i should consider? What gap would you recommend? Total seal tech said the top ring should be bigger for their rings (I would run .032 top, .022 bottom) based on their recommendation. Wiseco instructions recommend bigger on the 2nd ring (I would run .026 top, .028 bottom). Any help is appreciated.

Thanks,
James
