X'd thanx for your interest... i was talking to a 1/4 mile TOP FUEL driver who has been successfully in the game for over 20 years. i left him my XF for a weekend as the wife and i flew to the west coast... when we got back and picked up the XF he had left me a note saying...

yep a 3.8 MB will fit perfect in there...

so... began my investigation... i want to be familiar with this info, before he gets back from his travels...

this is a man who drops/pulls/ $55,000 dollar engines like its nothing. he has 5 in total...to be safe on race day...

so getting back to the threads orig topic... regardless how much one paid for their XF, this car has extreme potential. engine/drivetrain swaps...

i wouldn't mind dropping a more powerful engine...matching up to the orig tranny(!?)... for the weekend... and swap over to the 3.2 for the day to day drive.
