as you know I picked up a 355 world 4 bolt main block with titanium rods ,valves etc.
its a blower motor.
it got the AFR 220 competition heads.
I cant seem to find a set of headers to math the exhaust ports.
these ports are huge.
anyone know of a place that sells custom headers or a mfg. that makes them for these AFR heads?
and since i got the blower motor I might as well sit a 6-71 on top of it and run some fuel injection set up aswell

is the bolt pattern stock?
E

yes it seems to be a stock bolt pattern

Try www.lemonsheaders.com. They might have the capability to make what you need without having to have your car on site.

Also Stahl. You're in $1300 territory. Also, call Hedman and see what they recommend. They have larg(er) headers listed but it's tough to tell from just reading their site.

ok i found out that all i need is adapter plates.

i can then run larger tube bigblock style headers

That's confusing. What kind of adapter plate are you talking about? Just curious.

here is a link to the adaptr plates:

I think you may be a little confused about the adapter plates. They are designed for specific headers ie...Stahl (great headers by the way). These plates are nothing new and have been used for years. You will need to machine them to match your ports. Other comapnies make these adapter plates as well (hooker). In any case big block style headers will not fit on a small block (the port spacing is totally different).

Those heads are huge for a 355ci engine and just how big of headers do you plan to use? Is this a street car? What kind of blower drive ratio do you plan to run?

That clears it up for me. I thought no way, big block headers on a small block. I was ready to see that.
