If I had that I could run 9.70s and RJ could run 9.60's cause he is a better tuner. I guess you guys are in your right mind. I had a 35 Hudson Teraplane fastback with a V12 Hemi that got 10 off, and Sammy P. has gotten about 200 off that 427 thing he runs. RJ, nobody likes us old guys. I'm gonna complain to the AARP.

Jeff, unless I miss my guess, I'm pretty sure the 1000 cfm EFI throttle body does not have a big booster venturi hanging out in the middle of each of those 750 cfm Holley sized throttle bores. I'm pretty sure those are a considerable restriction.
