This is just another datapoint regarding the BBC vs FE conversation.
Ray Paquet crushed the NHRA SS/A record in October 2016 with his 64 T-Bolt and 427FE running an 8.53 @ 155.58. Whether he's in SS/A or SS/B, Ray consistently beats the BBC cars. The Hemi's Barracudas are the only ones that are faster, but only a select few. I agree that canted valves should be an advantage, but it hasn't proven out yet in NHRA Super Stock.
Here's an 8.60 run:https://youtu.be/IR_XgMuNdKE
