370 is 6.1
376 is 6.2

 

If the engine is not going to make power above 5500 then is 1 7/8" going to show any benefits over a 1 3/4" primary?

 

Its a LS motor they make power above 5500 unless factory cam

 

I'm not talking about that George. Im curious if a LS motor is going to show any difference in power with the 1 3/4" header or the 1 7/8" header. I want to make as much power as I can with the exhaust and the worry about the internals of the engine.

I dont want to re buy a set of headers if I dont need too. The exhaust says I need them, but who knows, he may change his mind once I get the headers off.

 

I went with 1 7/8 headers with my setup along with 3 inch exhaust and flowmaster hushpowers.

 

I see what you have there and I dont need all that I dont think.

I have a NOS plate on there, but I dont use it and only use it just for fun.

I have a chevelle for that.

 

Mine is my daily. I will only use the spray at the track. The Speed Engineering stainless LT's are the ones I'm running. The fitment was great and they are great quality. You have my vote on those

 

Thanks.

They sure do seem to outstanding prices. I cant believe those prices, they are cheaper than steel painted ones from Pacesetter and or Hooker.
