pushrods lenth for ls6 cam What length of pushrods do I need for the 01 ls6 cam? I was under the impression the 01 ls6 cam has a smaller base circle and therefore it requires a different size pushrod. BTW, this cam is going on a 4.8

LS6 cam with LS1 heads you would need a .27" longer pushrod than stock. you can buy a set of Thunder Racing's 7.4" pushrods which are actually 7.415" so then you would only be .12" off perfect valvetrain geometry. The difference will be absorbed by the lifters.
Hope this helps.

Sorry didn't pay attention but the TR p-rods will fit nicely
2001 LS6 Cam: 204/211 .525/.525 Int CL:118, Exh CL:114 LSA:116 Cam Base Circle: 19.3mm
2002 LS6 Cam: 204/218 .551/.547 Int CL:120, Exh CL:115 LSA:117.5 Cam Base Circle: 19mm
Now LS1 cams have 19.7 mm base circle so the 01 LS6 cam diff is .4 mm or .016"
So that would make the TR's even better.
