Both Ray and Tim Honed their Hemi Craft in Toronto. Ray use to be in the back of Knob Hill Speed and Custom on Eglinton Ave in Toronto and Tim was in the head department in Entec in Toronto. Really back in those days 70s you went to othesr in Toronto to have your Hemi build by Beatty and Woods. Donny Cloake, Frank Elliotte Garry Van Stone, Bob Braby on and on there were a lot of good builders back then. Ray fine tuned his Super Stock build starting with Donny MacCallum, Donny was first in the 8s, Tim had two professions before he started FHO full time. Tim and others revamped KB because there was no Hemi Block of any kind available back a few years. Tim years back started building mostly bigger cubic inch Hemi motors. At one time Tim had a 500 CI 14 71 Blown Hemi in a Cuda making stupid HP. Ray raced a 1965 B Body for a while I believe. Ray and Tim both know each other very well both sell each others equipment that they have designed for the Hemis. Both have built plenty of Hemi motors since both have been doing this since the 70s. There are other like Todd that build a good product. Make an educated choice on who you pick. All these guys build good Hemis and all are busy doing that.
