I am rebuilding an LT1 and need some help for a connecting rod. I read thru the searches I found but no real defining info given on what kind of rod to use for different set ups. Seems more like a personal preference, and opinion on company products. The engine will be as follows:

stock 2 bolt main block .030 over
Line hone mains ( studded main caps)
stock crank polished
stock replacement oil pump with white spring
Wiseco flat tops - 5.4cc Pro Lites 11.1 w / 58cc chamber (386g ) 3.48" stroke 6" rod
Ai cam 208 / 221 525"/ 540" 112LSA
Stock heads cleaned up flow about 240cfm intake 170cfm exhaust

This setup is going into a 95 M6 vert full weight DD with 3.42 rear, will have MAC headers, borla catback. Giving as much info as possible so I dont have questions posted for answers that I need.....

I need to know what rod would be a better fit for the set up and not sure yet but considering a 125 shot later down the road.

6" Scat Pro Comp I beams 7/16"
6" Scat H beams

The Scat ProComp are the ones with the capscrews right?
They will be fine. With that light piston and the low revs this will not be real demanding of the rods, those would be fine beyond what our pcm will support.

58cc chamber? They hogged out?

The scat I beams would be my choice between the two. I personally prefer the Manley Sportsmaster rods for street performance motors.

Yes, to the 58cc chamber question. So with the Scat I beams, they will be enough for 125 shot as well? I was thinking that they should be enough considering I am really not reving high, or pushing alot of N20. What do you think as far as Hp, Tq...?? I was thinking around 330 whp and around the same for wtq....is that a fair estimate.....tune with pcmforless and stock injectors....
Also, Wiseco does not list the piston as being capable of taking any spray....they are forged, lightweight, flat tops with 2 valve reliefs...strutted pistons....thats all it says on the website...Any thoughts??

Both the rods and the pistons will handle a 125 shot no problem. Gap a little on the loose side for the spray.
