Brace yourselves !

Yup ...it's new project time .

may have just kinda sorta bought this ..

hey ..it was cheap :)

engine is a 3.4 litre hemi head ..

Image


now cleaned up and reground and ported a touch...all cast iron ...getting that onto the bench and off the car was a nice bit of excercise its 118 lbs in weight.


plan is to make a new inlet manifold , give it 10 psi boost (it's 7:1 cr) and so my first question is , valve seat recession ?



as far as i know my options are ,

oil drip ..nothing and suffer recession ...water injection might help ?


so please tell me all about it .



regards
robert

That is a beauty, well, I'm sure it will be once you have done it! :D I would recommend a splitter with one pipe to each branch of the manifold, then probably a pumped (electronic) valve saver kit if you are applying a bit of boost. Flashlube was originally made for the transition from leaded to unleaded fuel so has to be the way to go. Keep us updated on the project; love to see this kind of thing brought back to life :wink:

Sorry i should have said , it's an Armstrong Siddeley Sapphire mk2 , 1955 . sort of a rolls bentley competitor , for the driver who didn't need to impress ;)

Thank you for the positive comments , i am most curious about how many miles could i do without any valve protection ? , and is there any other way to protect the valves other than the lube systems , which i assume will drop my octane a bit .


When it arrives the engine was locked solid , , so i had loads of fun trying to wack the pistons out from underneath , i only lost one ,

and now its honed ready for reassembly .

ignore the crack !

A dollop of Isopon should sort that piston out......

It might be worth speaking to a local machine shop about replacing the valve seats if you think its a problem. I gather its possible to cut the existing seats out and put a hardened seat in their place from conversations with the one I use. Same sort of thing that gets down to older vehicles that ran leaded petrol ok but couldn't cope with unleaded. Real question would be does it need anything though?

Armstrong Sidley Saphire, I was thinking more Anthill Mob car from Wacky Racers. Turbo'd should show a clean paid of heels to Dick Dastardly.

Unless you're going to be doing some mileage VSR might not be worth worrying about? Pushrod engine so relatively easy to pull the head for new valves and seats as Bri said or do as Mick (Fox vehicles) said with a lube system. Won't the engine design smoke a bit even in new condition, probably protect the valves a bit anyway.

yup i agree simon , it has no guide seals , although the guides are like new , it should self lube a bit , and mileage would prob be no more than a couple of thousand a year .so ill try it , and if i am adjusting the ex tappets every day , have a rethink.
