Would never dream of buying their test engine but use the idea
by cutting an LS block leaving the last 2 cylinders etc.

Sourcing a front end collision block, crank can be used with no snout
like latest bmw L6 which uses a bolt into the flush crank/front seal
which also incorporates timing cog. Lighter, no snout to worry about.
Chain cog with good fluid balancer should rid most bad vibes.

Heads even easier while cam again not difficult then you have tremec
bolt up, 2 exhaust for a front mounted turbo. 2litres possible using
8.2 litre version of the LSX crank or use damaged brodex speedway engine.

300hp should be nice from 50kgs with t5 box.
