Crossflow B-Series Parts

 

Having raced using a Peter Burgess built Siamese head engine which gave me the Club Championship in 2002, I decided to build a crossflow engine using an MSX Alloy head. This since the PB engine was in need of a rebuild and I might as well do something interesting.

The resulting engine was built using the best components and parts. Target BHP was 160 and it met or exceeded this target, with an estimated 165 bhp on the flywheel. It runs very smooth and strong and will rev until it blows up. I only rev it to 7000rpm, since I want to "be kind" with my stuff :).

This engine is now for sale. Pictures of the engine, whilst it was built, and the components that went in it are here below. NOTE: The head shown in these pictures is an original HRG Derrington from 1962. It is NOT for sale. the engine now has a brand new MSX head instead. A Full list of components is below the pictures.

Carrillo rods

Expensive. But using up to 8000 rpm and think about it as a life-insurance. Last thing you want is for a rod to snap and ruin all the expensive components around it.

Alloy backplate

About 30% of the weight of the original, steel, item. NOTE: This is an early style, for 3-synchro/MGA gearbox mating. It uses a slightly smaller flywheel as well.

Pistons, starter, etc.

This picture shows the light gear-reduction starter and the 020+ pistons. also visible are the two manifolds, dual SU and dual Weber.

Roller rockers

Roller-tip rockers from Harland & Sharp. The pushrods are chrome-moly tubular, from Iskenderian.

Rockers and head

Build progresses. I did at least 3 pre-builds before final assembly.

Thread chasing

All threads in the block were chased and cleaned for exact torque.

Painted block

Orange, of course.

Safest way to measure tightening torque is to actually measure fasterner stretch. During the process, you record the torque required on your own wrench and fasten all remaining bolts to same spec. Of course, you verify the stretch as you go along.

Alloy flywheel

Vernier cam gear

This item is available separately, as I later changed to a fixed camgear setup, with offset keys.

Components

I am asking $4.500 for the engine, minus the carburetors (Weber 45 DCOE). That does not even cover the price of the components. I can also take off any item you would not want, like the backplate, flywheel, rockers, etc. This will obviously reduce the price.
