I was thinking along the same lines, I've never had the bonnet for the car though so I haven't been able to test it just yet.
The builds been coming along very slowly unfortunately, but I'm starting to get stuck into it now, it went in for some rust repairs and got the chassis strengthened in 2014 but that's been about it.
Independent Motorsport down in VIC put the motor in the car in 09 before I had it, they've modified the sump though, looks like this one had a rear hump also, it got deleted and has been welded up to sit flat. The motor seems to sit as far down as possible, but it still seems like I'll have big clearance issues haha.
Also runs a modified nizpro intake which takes up a whole lot of room where the bonnet should be, so I'm thinking when I make a new exhaust manifold, I'll make it to try get the intake as low as possible, I'll have to move and modify the electronic throttle also to get that out the way as it hits the wheel tub.
I'm hoping to have this done by the end of next year haha.. hoping.
