Today was planned to be a quick few hours slipping the new subframe under the car and mounting the scrap engine in place so Nat of Retropower can build be some metal spaghetti (aka Manifold). Alas the few hours turned into a full day of trial and solution.
First off I washed down the gearbox to get the old oil off, secondly a quick acid wash and final wash down produced an almost new looking gearbox.
Next was to get the car up on axle stands and lower the old subframe out of the way.
Then mount the gearbox to the scrap engine and bolt that all to the new subframe.
Alas on our fist attempt to fit the subframe Martin (sicknote to those in the know) who was paying a visit to Retropower, and chipped in to assist, spotted that the subframe was too narrow to fit the car.
After several debates and even more measuring it was agreed the subframe was indeed now narrower than it used to be, (as this is the original subframe off the car and it fitted fine when originally removed several years ago). Obviously changes have occurred during its many modifications and welding sessions. The subframe is an earlier design (with more positive camber wishbone location than the later type one with more negative camber wishbones). The result is that the wishbone has now negative camber which is good but the chassis mounts are too close together, to enable the bolts to be correctly tightened up. We could of just forced the bolts into place and tightened it up, but thats not right.
The solution was to elongate the holes of the chassis mounts to allow them to sit wider (5-6 mm each side), and to nip a couple of mm off the bump stop arms that sit on the outer edge of the chassis mounts. The subframe now sits in the car 100% correctly now.
The gearstick comes out the tunnel hole where planned and the cam towers fit on the top of the engine without rubbing on the firewall / bulkhead.
We can now lower the car back onto its wheels and start looking at the space available for an exhaust manifold.
So a whole day and a right mess in the middle but the end result is job done, the templet block is in place and its now down to Nat of Retropower to do his magic on an exhaust manifold.
