Yeah crap weather this morning, it hosed down here. I'd left the BBQ uncovered last night, it's a bit of a mess this morning

That should go all right indeed, that's a similar engine combo to what the older NZ V8's had except they had a carby and slightly smaller cam and make some decent power. they weren't allowed to touch the heads at all, net even de-bur the suckers.

Where did you score that?

I'm still of 2 minds for my Senator, stick with the banana's or put something like that on it. I have a spare bonnet to cut a hole in if required

I'm thinking of going hydro-roller cam though.
