Looking for a Lpg installer in Cleveland for V8 hemi

[v8 jago]

Can anyone recommend me a good system for a Jeep 5.7 hemi in the Cleveland or northyorkshire area !
They must be ones that can run a hemi without switching to petrol everytime I put my foot down.

Thanks for that ! What company is he and what system does he use ?
