see thats the type of engine i would like. Something that would have to trouble driveing around any time I'd like. you said that fms build your motor right. how much did you say it cost you.

Ram 910 but its on its way out
, before/after numbers were pretty close to the same as afterwards but you have to remember that I added a 12 bolt and moly driveshaft as well as reduced my timing to 24 degrees (full time nitrous tune here) while at the same time adding the stepped headers and the 90MM setup. My cam peakes at 6400 and my valve springs are comp 978's and I'm even using the forbiddin yella terra rocker arms lol

I ask this because I have jet-hot headers which I think are 1-3/4", and I was thinking in using them on the 408.

Probably not but if you want to get all the power the engine can make you gotta let it breathe. I run the Kooks 1 7/8" stepped to 2" and I would have gone with the 2" if I could have.

True dat
I only have 1 3/4 grots on my 408 LOL but it makes 725 to the wheels so I am not complaining. I could make more with bigger headers IMO.
