Technical Board / General Technical / Re: GREY MOTOR ROLLER ROCKERS-DONE!

Hello all Been a while have been super busy. The FC has been going fantastic since the roller rockers were fitted, including a trip to Brisbane and back to Cairns, after 30,000 miles and plenty of rpm by Me and my Son, the old girl developed a compression leak into the cooling system. the head was removed, and had to be machined flat again. while I was down this far my son conned me into fitting the roller cam and followers that had been in the cupboard for years. the cam chosen is a Tighe billet camshaft with a 35/75 overlap and solid big block ford followers. the cam had another .30 thou lift over the previous solid cam and was only a 30/70. we found that the exhaust valves were going to hit the pistons, this meant that a full engine pull down to get the piston out and to get them machined for the extra lift. while the engine was ot an inspection of the lower end reveled that the bearing where still like new from the box(even after many visits to 6500 and beyond) a valve spring travel test found that the springs would bind and was found that valve seat pressure would not be sufficient for a roller cam. A call to my mate Pete in Brisbane who has earned his living building race engines found the right springs( from a Porsche inner and outers) would give a valve seat pressure of 95 pound. I also purchased some 8mm chrome molly push rods, I then had to machine out my adapter plate to fit the new push rods. The engine is assembled and in the car now, a aluminum radiator is being fitted and the stock fan will be deleted, to make up for this two 10" thermo electric fans will be fitted, the front opening had to be opened up to accept the new width of the radiator ( now it won't sound like a Cessna taking off) and will give a bit more horse power in the upper rev range. this time I will get a dyno run done as last time it was running so sweet! It now has .515 thou of valve lift. this should make it breath This is my initial build of an electronic dizy for the grey. It is a red motor housing, grey motor shaft and ford electronics and rotor cap(hybrid)! I hope one day to build a grey with electronic sequential fuel injection The guru in Brisbane estimates about an 8hp gain (what a lot of work for only a few horse power!!!)

Hello Alex, thank you very much for all the info you have found on my poor old girl. I have been looking for the CR#14 and hope to get some replies soon. I will be taking some pics on the weekend which i shall post after Monday, but please dont expect too much. It is redeemable but is in a pretty sorry state. Much of the car is original as per the article, but things such as wheels and seats have been removed. I have high hopes though! A closer scrutiny of the project will take place to see if i can handle such a task, i will let everyone know soon. Cheers,Bob Jamo

Hi to all and a big thank you to RET for doing a great job organizing the information so everyone can share the fun. The car is still going great,other than a tappet re-set it is motoring on mightily! No dyno yet, but that will happen soon i hope. I will post some pics of the car too, as it is not a bad looking old girl...(poverty pack version!) The wife helped me restore it about 10 years ago. As for the interesting front clip in the first pic... it was placed in the pic so as to try and arouse some interest, and to help me research the origins of this car. I came upon the complete car in a garage clean-out,although it is in a sad state at the moment.It is however redeemable, can anyone help with info and hopefully some pics? Thanks for the kind words and encouragement,more soon. Cheers, Bob Jamo(ocker)
