I have a chance to get a used but great shape lt4 intake. I was wondering if it can be a DIRECT replacement to my LT1 intake and if I will get any improvement in performance over it? I have lightly ported heads already, but wasnt sure if the lt4 will fit since its stock cast ports are for the lt4 heads right? Thanks alot---

 

LT4 intake wont line up with LT1 heads.

 

Yes you will need LT4 heads to match the LT4 intake.

 

LT4 intake wont bolt up to LT1 heads. It is a good intake with higher runners then a LT1.

 

ok, well oh well I will have to pass that one up Thanks guys--
