im just getting into a 355 build with a VT 5 litre roller engine from a 195 SS
I have the stroker crank which is 3.48 stroke
Main Journal: STD Holden
Con Rod Journal: STD Holden
to suit rods
Big End Journal: STD Holden
1st question is whats the STD Holden size?
as both my pistons and H beam rods are coming from the states they are all STD Chev size
H beam 5.7 rods
forged low comp 60 thou pistons 1.560 Comp Ht.
im going forged low comp pistons and i have noticed that with VN heads the comp will be lower. as VN are 64cc and VT are 58-62 cc is that right?
so VT heads will raise comp along with the 60 thou
and can i use 1.560 Comp Ht. pistons?
I know my block has clearances for rods but am i able to fit the 355 crank without machining?
last question for now whats a good compression for running turbo or turbos? with the plans i have it will be approx 9.4:1 is that ok? from the research ive done it seems to be a good number
any help would be great guys
