The TF And FC engines are not Mopar engines..BUT, the heads ARE the BASIC Mopar desisn and THAT was the point ! No body is saying they are 'Dodge" motors, what they are saying is that they ARE Mopars design,..and they ARE ! IF there was something better out there , they would be running them. NOTHING flows like a HEMI ! I talked to Herb McCandles at lenght one day at tri-State in Cinncy. a few years ago and he said the cry-babies (GM, Phord ) camps, were So loud that NHRA factored and re-factorerd (three times in one season) Mopars to the point they were uncompetitive . This is in Prostock in 1974..that is why he got out of racing. He said the Mopars had to be heavier and with smaller engines . He said " AND we were still winning" , What a statement against GM , Phord ! The last thing he said was that "the NHRA was going to have the Mopars pull a sled with bricks stacked on it so they could adjust the amount of bricks to suit the different tracks to keep Mopar from winning" ! We know he was joking..but the image of that is hilarious !! How embarrasing to GM and Phord to have to win that way ! Just about like the situation today with Harley Davidson and NHRA. HD's are 2600 CC and Suzuki's 1500 ?? The HD's are overhead cams and four vales..just like the Suzuki's !
