im putting a LS1 in a 75 camaro would the shortys collecetor flange interfere with the
frame or tranny/bellhousing being so short probaly useing one for a 5.7-6.0L
truck or F-body shorty header application?

 

Shorty headers are usually have the same location of the flange's as stock manifold, so. they should fit.

The F-body should work ok, but the Truck Shorty and stock manifold have a more rear facing exit and could run into contact with the firewall or frame.

 

Thanks

 

camaro, you may want to just start a thread about your build and ask all your questions in the same thread. It is getting harder to follow your questions. The shorty headers should line up the same as the manifolds, but testing has shown no real performance gain with a shorty over the 00-02 manifolds. Only a longtube showed any gains. Even the mid lengths like we used didn't really provide a lot of gain, but they made the swap fit, so worth every nickle.
