ok getting ready to work on a firends truck.
has volant cai. ported tb.
we are putting in a 208/216 500 500 113lsa cam with 1.8 crane rockers
adjustable double timing chain
lpp long tubes and offroad y-pipe
corsa cat-back.
and nelson tune

my question is how much HP and TQ do you think we will pick up??
thanks larry

 

in what engine?

 

oh my bad. 2004 silverado 5.3L

 

lol, im so dumb sometimes. lol

 

~45hp? Why go with the 1.8 rockers if swapping cams and not just by the cam he wants?

 

he talked with vinci and this is what they sold him. i would have put in the comp 216 220 532 14lsa cam if it would have been me.

 

he wants more power and tq for pulling a rv.

 

what did they tell him his gains would be?

 

With approx 530 lift w/ those rockers, Will he need to change the valve springs...?

 

Yeah man he has new valve springs and pushrods to.
