Bowtie Brody's Namesake 96 454

The thread associated with that pic was interesting as well.

Yes it is. If I followed it correctly he actually ended up with shorties not the cool long tubes in the above picture? And with the headers and tune he gained 42rwtq. I wish he'd separated out the header change from the tune. I don't remember any mention of downstream changes like mufflers or tailpipes. Even if he didn't, I think the 8.1L's have a larger diameter tailpipe.

I know most are probably familiar with the banks system, but a data point for intake inlet and downstream exhaust mods. Their claim is for up to 49 lb•ft gain in peak torque on a L29 7.4L, a similar 12% gain that Waffle saw on clincyoffroad.com with his shorties and tuned 8.1L. Just beware of the risks involved in running the more open lower efficiency air filters in dusty environments.

Correct, ended up with what he called midlength JBA's. And yeah that would have been nice if he would have kept stuff separate, would have been easy enough to do too. It sounded like he kept the tune fairly conservative though, so at least some of the gain can probably be attributed to headers.

I wanna know if these ******** will fit a 7.4 in a GMT400.

Doubt it, without some level of cutting and welding, but they shouldn't be too far off. They should bolt up to the heads just fine since the 8.1L uses the same heads.

I just wonder what would interfere. Don't have an 8.1 GMT800 here to compare to.

I thought the 8.1 changed head bolt patterns?

 

[Christian Steffen]

****, could do custom? It would take some time, but you'd end up with some badass headers.

It'd be easier to chop on a header that probably 90% fits already.

I was wrong that they are "the same" but correct that the exhaust bolt pattern is the same. I really need to stop going from memory.
