project 500 Mk1

well Im not sure I actually need 500 horsepowers, but I might as well build the short engine to handle it. Parts have started arriving at the London 4th floor flat, the missus is pissed that there is an engine stand in the corner of the lounge and that attached to that is a 4x4 200 block and 2wd sump and it's internals are spread through boxes around the place.
Also Picked up an unmolested head with mountune race cams (bd15 and bd16 equivalent), solid lifters and lightweight vernier pulleys. and just awaiting the 4x4 inlet plenum of e-bay.
I am planning to long stud the block while it is being prepped with line boring, and a basic rebuild with new accralite 8.5:1 deep valve recessed pistons and balanced internals and multi layer gasket if necessary(the block has been o-ringed so yet to determine what gasket). To this Im going for a lightweight alloy flywheel with steel insert and quartermaster or AP 7.25 inch lug drive twin plate clutch. Turbo wise probably a T4 or similar and aftermarket computer running greys or light blues or similar.
In reality Im only after/will achieve 350 as the Mk1's tyres are only 7 inches wide so much more will be a waste, but I might as well build the bottom end strong enough for 500, while im here in the UK.
Some photos.

nothing like a long overdue update.
I have spent this year collecting parts and serching for a decent engine builder. So far I have collected the following:
AP CP5200 calipers for 310x32mm disks and alloy brackets to suit


T34 Garret 360 degree bearing


AP racing 7.25 3 plate clutch and AP ultra lightweight flywheel



6 Revolution 15x8


Also collected a reprogrammed ecu, green 803 injectors, 3 bar map sensor, more ARP fastners than I can poke a stick at, head studs, main bearing cap studs, flywheel bolts, cam caps studs, a T5 gearbox, 2wd exhaust manifold, 4wd inlet manifold, 14mm manifold spacer, freshly powdercoated black rocker cover, new alternator, startermotor, 2 round headlight grilles, a grp 4 steering coupling, double valve springs,complete set of new sensors, rebuilt distributor, 2wd wiring loom, turbo hangar and new stainless steel bolts for the block and black for alloy parts complete new cosworth gasket and seal set.
Hoping to get the engine builder to accept delivery before christmas!
Probably not going for 500 just a sensible 350 as I cant afford to redesign the rear end or the gearbox.
Am looking for a Tilton T5 hydraulic clutch bearing assembly, and alloy brake disk hats and possibly a dry sump assembly.
cheers,

Decided the best way forward was a new cosworth head. the original one is an unknown quantity and this came up at a reasonable price. Im the third owner but its never been fitted to a car. To my surprise however it arrives having been ported to similar dimensions as described in Des Hammills book. Engine builder is to check its been done properly but my lucky day I hope as it saves me much cash not having to have it done.
The crank and flywheel has been balanced, the crank having been balanced before but the combination was significantly out, engine builder suggesting it wasn't done right originally. Fortunately however it checks out straight and only required a polish of the journals. The pistons are now being pocketed and the block is having the long stud modification done...photos to follow.

Looking good.

Is your block lined ? What pistons did you end up using ? and if you don't mind me asking where did you buy your new head from ?

Thanks,

Damion

some more progress,

dummy build to determine valve reliefs and cc'ing etc mountune long studs x6


Example of proposed valve cutouts, yet to be machined.


Bottom end all dummy built up to check clearances. rods balanced new little end bearings just to be sure! ARP main studs and ARP rod bolts

Looking good.

That lower pulley looks big - might be a squeeze to fit behind radiator?
