I am in the middle of my engine swap. 99 Sierra was a 5.3 now a 6.0. I have everything for the swap but now what about the fuel system.

I was looking at switching intakes from the ugly truck intake to an LS6 style intake. What are the benefits between the two performance wise? Is it a straight drop in and go or is there more things involved?

Also what about the throttle body should I get a new one? What mm?

I have a set of low mileage 2004 6.0 injectors. I think they are 24lbs. Will these be suitable?

Thanks for the help.

if your cam needs it use it if not dont. i chose to use it for my 6.0 as for swap i did the whole fbody conversion but others do the make it fit setup

 

What do think about the f body set up. Did you have any clearance problems.

It seems that the f-body and vette intakes throttle body flange sit lower than the trucks? Looks like it may cause clearance problems with the water pump. Not sure though can anyone clarify or have pics?

 

direct bolt on but had to lenghten the ALT wire since its down lown now

not the best view of it tho

 

did you have to use the f-body injectors? Nice truck By the way

 

i used SVO injectors, and i got my plugs off a 4banger s10/camaro

thanks

 

Is there any rewiring that needs to be done before using the SVO injectors?

 

yes you will need new connectors/plugs
