Im looking to do an intake manifold swap on my truck, but before I do I want to know which one flows the best. And is it easier/cheaper to do one over the other. Ive done a bit of reading on this lately and was looking pretty hard at doing the tbss right now, before I upgrade my heads, or I could pick up a set of l92's and l76 and call it a day.

Just looking for any light to be shed on this subject

oh im not even sure if the l92's work on a stock 5.3, but I do plan on going to a larger bore in the near future, just want to get what I can get out of the 5.3 for now.

 

here you go all the info you need to know and alot more.

thanks.... I hadnt ran across this yet

 

its in the stickies thread but they put them all on one thread used to be at the top of the forum i had the same questions a while back and this helped me figure out it really aint worth goin with any intake besides the truck unless you are runnin above 6k rpm or goin with the l92 l76 setup and then you obviously have to go with another intake. you are not goin to be able to run the l92's on anything under a 4.0 bore so unless your goin 6.0 its not gonna work .

 

from what Ive just read in these threads, it probably isnt worth it unless i would go FI which is not planned at the moment... thanks for the l92/l76 info too, I thought it needed a 4.0 bore but wasnt 100%.. looks like my intake manifold questions are done until I start building my new engine.
