shorty headers are a waste of money, they show no real gain over stock manifolds. the lts keep about the same low end torque but really help in the upper rpm range. basically its just a better flow all around and your able to make more hp/tq with your setup by running long tubes vs a stock manifold/shorty header. just my .02

 

why would you run ngk?? compare to the stock ac delco iridium

 

2.25 a plug vs 7-9 a plug plus i spin my motor pretty high and the iridium plugs i had didnt last 10k miles. the gap of the NGK TR55s iridiums i put in my truck when i first put my motor in was at .050" and now its .063-.064" i run 93 octane, and 24-25* of timing so it should have lasted longer than that. i dont know if the 6800rpm helps it any

im pretty mad that the 70.00 in plugs didnt last worth a crap so if im going to be changing plugs every 10-15k miles id rather spend 20.00 on the NGK TR55-6 plugs and be happy that i still have an extra 50.00 in my pocket

 

Mmm I guess.. Well when I I did my headers it had 30 k.. I change plugs because z
They were gone... Koo thanks I may try it next time I do my plugs.. But I can only do 6200 rpm :-(

 

why only? if the truck keeps pulling, spin it higher

 

Stock 5.3 cam started fallin off fast after 5600rpm when i dynoed my truck. Im guessin he still has the OEM cam.

 

Yup no cam yet.. That's how B.B tune it to be safe..

 

mine pulled just fine i guess thats because it didnt have an azz to it anyways so i couldnt tell if it was falling off


so what are you waiting on?!??! do a cam swap buddy! lol

 

Start with a tune then decide where ya wanna go from there............
