Not much done since last update what with having a cold then having the flu and don't forget the nice cold weather outside, with it being so cold and wet outside I decided that the wiring could wait until it gets a bit warmer ( probably next year ) and have started on the interior trim repair's.
First thing was to tackle was the damaged and cracked dashboard crash padding.

The loose plastic was first removed and the foam underneath ground down slightly, then all the cracks were ground right down with a die grinder.

Next polyurethane was melted into all the damaged area's with a plastic welder then flatted of to just below the level of the plastic finish with a power file.

This was then filled with flexible filler ( the type used for repairing bumpers ) and then sanded by hand to the same shape as the original finish.

This will get painted with texture paint at the same time as the other parts are done. The interior trim parts still to repair are, both door trims ( one very badly damaged and both slightly warped ), rear b-post to rear wheel arch plastic cover ( just needs covering in texture paint as all the texture has rubbed off ), rear shelf plastic trims ( same as the plastic covers ).
On another note I have started sorting out parts for the engine. I have bought the cylinder heads, but I did the one thing I said not to do I bought them with all valves in ( they were a silly cheap price with all the valves in ). I am now in the process of pulling them apart to double check valve fit, clean any casting flash off them with a die grinder and get rid of any sharp edge's and radius oil drain back holes.

Also the engine block is now with the machine shop to be re-bored. I have decided to fit hypereutectic pistons made by speed-pro ( H555cp ) and plasma-moly rings ( r-9903 ), when the block is back I will be ordering a set of eagle con rods ( 5780f3d ) to complete the bottom end build.
Next I have got to choose what camshaft to use, these are the spec's of the ones I am looking at :

At the moment I am leaning towards the Lunati cam as I have been told that a split pattern cam with a wide LSA and low overlap will suit my heads the best and give me the good vacuum at idle to work my power brakes and maintain low speed drivability, but if I do not go for this cam it will probably be the Schneider 254-74f cam as I have also been told that it is best to have the exhaust valve opening at around 80 BBDC because the later you open the exhaust valve the more it causes high RPM to drop off.
I will also be changing the toque converter to a higher stall to match whichever cam I fit and I will also be changing the rear axle ratio to suit as well.
If anybody has any feed back on these cams or know of any other mechanical flat tappet cams I have overlooked please let me know.
