Hi, my name is Phil Horsley better known as the Grinnall Nut, my mission to find the 330+ Grinnall conversion created by Mark Grinnall during the 80's & early 90's.
I own three Grinnalls, an early Body style 2 and two of the last Rounded Body Style 5, the latest purchase, known as 'The Beast', it was Mark Grinnall's demonstrator, 4.5L injection it certainly scares those Porsche drivers, all three put a serious GRINNall all over my face, certainly muscle cars and arguably where the TR7, TR8 should have progressed to:
If you think you have a Grinnall, know of one or just want some information or guidance, please contact me and I'll be glad to help out.
Go on, get one, you know you want too!!!
