I am planning a build for my ls1 and plan on using an ls6 intake. What are the pros and cons from any body that has done this. What size are the throttle bodies on the ls6? Does the ls1 throttle body fit on the ls6? MAF sensor..ect..ect

 

yes the ls6 is the same size TB as ls1.. just need to reroute the coolant lines under the intake.. since the ls6 has a flat bottom and the ls1 curved

 

75mm I think. If you don't want to grind the ribs off the bottom of the LS6 intake, just get the coolant crossover lines. Takes the guesswork out of figuring out where the LS1 coolant lines would run.

 

you can run a 85 mm tb on a ls6.a person on another site did alot of intake and tb dyno testing.the ls6 intake and a 85mm is hard to beat.
