I am going to install a GM 847 cam in my 95 z the heads have been ported by LPE and i wanted to know if anybody has had any piston to valve clearence problems with this cam. I plan on using 1.6rr and the springs are good up to 630 lift stated by LPE . Any info on this cam would be great like power gains and how well it works with N20 . I would like to get 400rwhp with this cam and heads and all bolt ons and stock bottom end.

 

ttt

 

whats the lift on them? stock bottom end i assume?

also, please only "ttt" once every 24 hrs

 

lift is 234/242 and dur is 575/595 with 1.6rr and yes it is stock bottom end ... I only ttt once on this thread and it was on the 4th page i have more than one post.

 

i think the durration is 234/242 and the lift is 575/595, unless you found a way to put 2 cams in there or make a circle 600 degrees




that is a lot of lift... but i dont forsee a problem. I am pretty sure guys are running close tho that lift than that on stock bottom ends around here.

 

oops sorry lift is 575/595 and dur is 234/242 thanks for the input
