i have a 5.0 motor out of a 92 mustang its strokedto 347 .30 over kb pistons with valve releaveswith victor jr aluminum heads 2.05 1.60 what roller rocker ratio should i use? and why?

 

100% of that answer depends on the cam thats in there. btw victor jr. heads are nice, that things gonna run pretty nicely when its together

 

im usin a cam from comp cams part number 35-450-8 i dont have the specs infront of me

 

It's probably meant to use 1.6 ratio rockers..........

 

yeah i looked it up and its .598/.598.......... you dont need any more lift than that LOL

 

I dont think your going to be able to fit those heads on that motor.... I believe your gonna need atleast .040 overbore... I heard rumor that large 2.05 valves will flow badly on small bore motors..... you MAY want to consult an experienced engine builder before going any further

 

meh, i wouldnt worry about that, the main thing that effects flow is not having the chambers in the head unshrouded..... which isnt a problem on aftermarket heads designed to work with valves that big.

btw the dif between .030 and .040 is only gonna be .005 on the side where the intake vavle is, thats not enough to mean anything at all.

no TS for you today Adder?
