I Have read over and over again that the ZZ4 cam is such an inofensive little camshaft,i want a good streetable but more aggressive camshaft,of course i will have a new tune from I have Edelbrock 4246 elite series centerbolt covers which i love,with the new lift,should i get a tall design cover ? Since i have ZZ4 Camshaft and LT4 Springs,are the LT4 Springs (blue line) capable of handle the 1.6 Rockers ? Heads has removable studs or not ! Hopefully someone can confirm this,if not i will stay with 3/8 studs. i was told to upgrade the studs to 7/16 but im not sure if the 128 i don't now if i need Self aligning roller rockers or normal ones, I will add brand new hardened pushrods as well 30 over now a 355 i decided to get some more into the old L98 to end this year mods. I really like how the L98 is coming up! i added Bosch III injectors from really fire the engine up and it feels powerful than before.-įrom a stock tired motor,i bored.
