Really nieve question which I havent given much thought to... but heck..

I hear that the B200 and B230 blocks are physically the same size. Are the cyclinderheads the same size/ or is the spacing of the manifolds and bolt pattern the same for the B230 as for the B200?

(If not i guess it means I wont be able to have the B230 in my 360 straightaway and ready to drive without getting a custom exhaust with manifolds made).

Any thoughts? I needs some knowledge mann

You can just plumb in the 2.3.. Manifolds are the same. Just make sure you'r not running lean. Easy powers man!

Sweeet man cheers! I was worrying about it but now i can budget my project more gradually phew!
