Rohan "The best option in my opinion is the McCoy"
I live a little north of Mr McCoy, have corresponded with him off and on and keep careful watch on his doings, both on the track and in his 'shop'.
While he enjoys flinging his Lotus Cortinas/Escorts around various tracks, he has never lost sight of the rigid engineering principles and application required for them to do so.
No competition implied/inferred or wanted twixt Dave Bean and
https://omnitech-engineering.com/ - both supply to us Lotus nuts...but while I would happily install a Dave Bean Twin Cam in one of my deserving Lotus, I would probably keep one of John McCoy's offerings for quite a while - uninstalled.
Just to look at...and possibly, accidentally rub against as it sits in my garage...hey - It can't just be me - can it?
Omnitech produces, for me, that mix of form and function...fabulous engineering tied to a great appearance.
(send the usual cheque to the usual place John...or better yet, next time at Mission, you can buy me a hot dog)
