305 to 350

Im installing a 350 in a 92 rs camaro 5 speed, will the trainy bolt up? what kind of headers can I buy thats still smog legal, because when I search eldelbrock they dont show headers for a 350 in a 92 rs, or will the same headers for a 305 bolt up to a 350? I sure could use all the help I can get. My other camaro was stolen about 3 years ago and I want to do this one better. thanks!

Same stuff I went through.

The Tranny will bolt up. I can't recall having any problems with this

SLP, Edelbrock & Hedman all have Headers for our cars.
Edelbrock - PN#350-6876 (Jegs)
Hedman - 500-68481 (Jegs)

Do you have headers for a 305 right now. most 305 headers will bolt right up to a 350 it just depends on primary diameter and collector diameter. If they are to small they can restrict a 350 badly.

Everything that bolts up to your 305 can be used on a 350. This includes any header tailored for our cars.

Header style doesn't matter. If you buy any set of header that is made for a 3rd gen V8 it will work on a 305 or 350 or whatever small block you choose to go with.

I was told by another person be carfull on that issue because the 305 head port holes are smaller then the 350 head port holes and this would cause a bad restriction? so is that true?

There aren't "305" headers, or "350" headers, just "small block chevy" headers of different sizes for different applications.
