I am building a 425 stroker with WCCH stage 2 L92 heads and a fat nasty cam and was thinking of going with a 2'' LT header vs a 1-7/8. Is this a good decision or is that too much for my CI?

And for those, if any, who are running 2" headers LT, what issues came into play? I will be using plates instead of solid motor mounts so I don't think room will be an issue but then again...

Thanks!

 

I will be running 2" to 3.5" collector. Motor in sig. Have not heard of any problems.

 

Not exactly what you're asking - but I stepped up from the pacesetter 1 3/4" to Kooks stepped 1 7/8-2" on my 416 w/ tfs 235 heads and a 244/250 hyd roller cam. I was dissapointed with the "gains" - haven't taken it back to the dyno but very similar track conditions yeilded no trap speed gains. Probably would've been better with just a 1 7/8" primary or smaller step. But take it for what it is - my intake is restricting me as well.

 

2' is going to be a great header for you car will hitting it with a big shot.

 

yeah i've got 2" on my 454, your motor will do well with them too.

 

Ditto 2" primaries on our 454 as well.
