I'm a little worried about the valve springs. It's got 1218's on it currently, good for .600" lift. The cam has right at .600" lift on both sides. But I was told that the cam works well with comp 918s and springs with equivalent pressures which the 1218 does. I'm just wondering if maybe i should buy a set of the 1518s which go to .650"? Do you have any 7.4" pushrods? I think my 7.375's will be a little short for ideal preload.

 

I'd definitely get something with .650 lift to give you a little room.

 

the only 7.4 pushrods I have are stockers but honestly, I've ran stockers with everything, unless I needed different length pushrods because of rockers or milled heads or something. People dont give them enough credit, the stock pushrods are pretty tough. and I agree, some .650 springs will help a good bit, but if you only plan to run them for a short time until you swap, the springs you have now will be fine IMO. The lift was .580's right??

 

lift is .597/.598"

 

one thousandth difference? who spec'd this thing for you?? is it already getting done?

if you want, call me this evening and we'll get you some better numbers.

 

the cam is already on the way baby.

 

that'll work!

 

Ben you forgot to mention that the sock trans was slippin when it ran the 13's too.

 

true true... it was slipping BAD... no reason that truck wont go in the 12's on motor once it can breathe. maybe even before then
