Greeny’s beast of a 355ci Iron lion. Going in his manual VK SS.

Coming in as a pretty tired 308. We made the decision to step it up a little 😉 By pretty much only using the block 😂

✅We started off by acid dipping the block to clean it up. Then fit a set of CRD engineering four bolt steel main caps with ARP main studs

✅The block was then bored, torque plate honed and zero decked

✅The rotating assembly was a S**t steel crank with H beam rods and Malie flat top pistons which were balanced.

✅The cylinder heads were swapped out for a set of VN symmetrical port heads. Which we sent to James who did an absolutely magic job on the ports and chambers. The seats were cut then assembled with Ferrea valves and Crow dual valve springs.

✅Some other key parts to the build were
- Crow hydraulic roller cam
- Johnson lifters
- Yella Terra roller rockers
- Roll master timing chain
- trend push rods
- Cam bearing oiling mod
-JP HV Oil Pump
- Proflow billet timing cover

✅For ignition and induction
- MSD dizzy
- MSD ignition box
- MSD spark plug leads
- Port matched a Aeroflow dual plane intake manifold as we had to keep it under the bonnet
- Quick Fuel 750cfm carby

✅ Compression ratio was 11.2:1

✅After that was all buttoned up we took it up C&R Motorsport Developments, Engine Dyno
And from there Geoff dialled the big girl in👌🏽. Making 501.5hp and 424lbs/ft of torque.

Gonna make for a pretty tough cruiser 💪🏽

This thing is next level🥵. BMW S58 with a stroker kit and LA sleeves.

What we did?
✅ Align hone with ARP main studs
✅ Machined the block to fit the LA flanged style sleeves
✅The Torque plate was cut out thanks to . And then finished machined
✅The stroker crank and rotating assembly was balanced
✅The torque plate was installed with the 625+ ARP head studs for the final hone
✅Then the block was decked

Very keen to see what can do with this one💪🏽

Gav’s very tidy little 347 Windsor going in his XM coupe. Getting all sorts of goodies.

✅The S**t Stroker kit was balanced by Pete 👌🏽
✅Block was then align honed with a steel girdle and ARP main studs
✅The stoker kit was dummied up in the block to determine the deck heights
✅The deck was then machined and corrected to a Zero deck
✅Cam bearings installed
✅Bearing clearances were set
✅Edelbrock Performer heads seats were recut and port matched to intake manifold
✅Heads were faced to bump up the comp to 10.6:1
✅Onto final assembly
✅Degreeing in the Crow hydraulic roller Cam with a set of gaterman lifters
✅Meilings oil pump with ARP drive
✅Cometic MLS head gaskets held in with ARP head bolts
✅Comp roller rockers
