i am getting a fm13 cam on a 111 LSA. and a set of PRC dual springs. which pushrods from Futral Motorsports should i get. the 7.400" stock length or the 7.350" ? also wanted to get a new timing chain in at the same time. is the rollmaster single roller non adjustable a good choice or should i get the double roller adjustable one?

 

hardened 7.4's if ur heads have not been milled. A single chain would be fine.

 

LS2 timing chain performs as well as any aftermarket one 5X the price... thats whats used on my car....

 

Replacement chain from GM for all LSx motors is now the LS2 chain and it is plenty.

If your heads are unmilled 7.40 it is. (best call Allen at Futral to verify)

 

I too am going with what the others have already mentioned.

 

ask Allan.
