This was a b series head that I had cut down the middle of number 4 cylinder, this enabled me to make cam swings and see the results, all data was then plotted on an excel spread sheet.

IIRC the big power was made using pro3 cams, I then had to change to a pro 1 cam because of lma contact on the valve spring retainers which I’ll have pictures somewhere.
 
After the initial Dyno with the pro 3 cams and a test day I noticed the valve spring retainers had some small nicks on the top of them.

The rockers must of been touching them at high rpm. So I took some material off the underside of the rockers to help. Also changed to a pro1 cam to bring the power curve into a more usable window.

It was all going great, then on a lap coming over Avon rise I went to downshift and the gearbox exploded.
I found the cause, a £10 spigot bearing in the flywheel for some reason seized causing the gearbox to rapidly slow down and bang the rest is history.
Probably my fault I must of installed it wrong or damaged it maybe.

This all happened on March the 16th 2020, obviously Covid19 / lock down happened a week later. It was at this point I had to say nope no more and pulled the plug on it all.
