The V8 Owners Forum -

Tony,
Give this lot a try,
they do most of my machine work when I need it doing,
http://www.thurstonengineering.co.uk/

Cheers Ian will give em a try,

just spoke to Ray at V8D,
and had a nice chat, for £1500,
they will tophat liner the block,
swap the pistons over to the other rods, and fully balance the bottom end . (front pulley, flywheel, crank, pistons and rods clutch cover plate)
he said if i thought it revved well before it will defo rev better when i get it back

Thats a bit dearer than turners but its fully balanced too

need to convince the wife now though to let me have the loan

Dont know what to say Tony........

Nowt anyone can say mate,
whats done is done,
need to get the readies saved now to pay for it,
means the car wont get painted for at least another 4 yrs now,
will be spot repairs for now,

you could look into selling the wife and kids to fund a new engine......


joking aside, its bad news to see a band new motor ruined so soon. At least Ray will build you a good base to build upon.

yeah i told him about the 4 valve cut outs in the pistons, and he said seen loads like that dont worry,
asked what the engine was going to be used for, told him about the charger installation (be end next year now due to this, unless i win the lotto)
thats when he suggested that be best to balance the whole bottom end assembly,

or am i better off sticking with the 4.0 pistons in the 4.6 block?

What are your supercharger plans for the future Tony cause 11:1 cr and about 6psi boost will do 15.5 :1 corrected cr so if you want to boost you'r better of with the stock 9.35 cr pistons which will do 13.2:1 corrected cr and give you some play around if you want to increase boost after a year or so...

I'd say get two new liners & stick in the original 9.35 pistons & get ready to get boosted in the nearby future....
Probably cheaper to....

But thats my 50 cents........

the overlap on the cam helps mate,
and Mike and others on here have assured me the 4.0 pistons with 6-8psi will be fine,

The loan has been accepted,
need to run the block to an engineering company in readin on saturday as they want to quote for the work to,
failing a good quote, its on a pallet to V8D end next week,

Next question, any one know any good couriers?
and prices??
and what will a block, crank, 2x sets rod pistons, flywheel and pulley weight?

also where can i get the replacement dowty seals from for the cross bolts?

and whats the torque sequence and torque for the side and main bolts?
i gather they need to be done up in a sequence?

and lastly the big end bolts, torque....

trying to get all my info together ready for the build,

Real Steel do the cross bolt washers

Cross bolts torque.
stage 1 10 lbft
Stage 2 33lb ft

Con rod bolts
stage 1, 15 lb ft
stage 2, further 80 degrees

Main bearings 1-8
stage 1 initial torque 10 lb.ft
stage 2 final torque 53 lb.ft

Main bearing (rear)
stage 1 initial torque 10 lb.ft
stage 2 final torque 68 lb.ft

cheers Denis

Ta mate,
is there an arp replacement bolt for the 4.6 rods yet?

dowty seals should be had from any hose place i.e : pirtek

My local hose place had millions and they cost naff all, dont mention Pirtek

will i gain anything by using the spare set of ARP mains studs on the 4.6?
or is it a waste of time being its crossbolted??
