Big horsepower 318 builds
RRR, have a serious question though... i'm a ******* idiot and do everything wrong and looking at my receipt for my heads i bought the TF's with the flat tappet springs, i know it just comes down to rate and such and i think they are fine. If i did my math right way back my OTN pressure is 305#,
Cam is small .525/.532 but howards doesn't list a spring rate/pressure (might be on the cam card at home)
This is the spring spec that i got, their hyd roller spring they list is about 20lb difference across the board.. i think i'm just making myself worry over nothing though..
