After much dreaming and planning I've finally bit the bullet and purchased a Rebello 3.0L Stroker kit. It's second hand off another user here on HybridZ, but it comes with the Rebello offset ground crank, eagle connecting rods and JE forged pistons. The specs on those are as follows: (I need to double check with rebello but to the best of my knowledge it's all correct)
Crank stroke: 81mm
Rod length: 137.7mm
Piston size: 89mm, pin height: 28.9 (this I'm uncertain about)
The kit is currently in shipping, so I'll update with photos once it arrives! I'll keep this thread posted as the build goes on as I figure documenting this process couldn't be a bad idea, it'll also be a great hub for all the questions I'm sure to have.
At the moment I'm keeping my eyes open for an F54 block or whole engine to be a donor for the process.
I'm also debating which one of my cylinder heads I should be using for the build, I've got two options and two more entire heads for spares, also whichever head I pick would get Schneider valve springs and retainers as well as my comp cams camshaft with the following specs:
Dur @ .020 292 int/exh
Dur @ .050 246 int/exh
Lift .480 int/exh
I've got a P90 that's unshaven, it's been cleaned and lightly ported and in overall great shape. Would just need rockers and a cam, though it would seem that my compression figures would be quite low on this setup due to the low pin height of the pistons
The other head is an E31 that's down to the bare casting, it would need to be gone over by a pro. 5 of the cylinders have been ported pretty heavily and the 6th one needs to be done to match. It needs bigger valves and hardened seats, as well as the cam towers properly installed. More of a project but according the the Z engine calculator it would seem that with a 2mm HKS gasket I'd be looking at 9.29:1 compression which would be perfect for pump gas.
