Bigflop 288 Posted June 4, 2017 Nason fuck me had no end of dramas with those fucking things in 4.0's theyre a lifter with a built in tick from new Agreed. My mechanic binned them when he done my cam. Went with stock ones.Sent from my SM-G935F using Tapatalk 1 Outback Jack reacted to this Share this post Link to post Share on other sites
broken-wheel 659 Posted June 4, 2017 imho the first part I would spend money on an XFLOW would be the following: Exhaust, Ignition (MSD with XF dizzy), cam and here are the reasons Exhaust, this is really bad on a stock car, the tailpipe is smaller than the carb, i think it's the same size as 1 carb throat and there are two, you can pick up around 35hp with a good exhaust with nothing else but you will have to up the jets on the carb, if you put a 2.5" exhaust with headers you would think the car is worse than before, flatspot on take off and just not as much torque but this is because it now runs lean, you need to check and will find out that you need quite a bit more fuel, once this is done she will fry the rear end on take offs...from the exhaust alone Ignition, this is another weak point, the chopper wheel dizzy has more play than the other and it's not very stable, the MSD makes the engine come alive, much smoother to rev and more drivable overall Cam, the stock cam and lifters are made of cheese, they wear out extremely quick and give you a nice lumpy cam sound/feel but robs a lot of power and will eventually bend pushrods. Isky or Crower lifters are good, would not buy anything else Share this post Link to post Share on other sites

broken-wheel 659 Posted June 4, 2017 when it comes to valve train this are my go to parts and i have never had any fail Rockers: Comp 1830-16, Lifters: Isky SO382-H or Crower cool face both items are bulletproof and have never seen them fail, both are steel and not the lightest around but they will serve you well, I never liked alloy rockers with flat tappets or solid roller 2 CHESTNUTXE and Outback Jack reacted to this Share this post Link to post Share on other sites

deankxf 20,350 Posted June 7, 2017 the est dissy didn't have the TFI module on the side, but i think i read somewhere it can be used also but no idea how on either .. the EFI one has the TFI module on it.(efi from XF onwards) edit.. found a pic i posted yonks ago.. might help?

SLO247 1,713 Posted June 7, 2017 You need one from an XF or ZL with EFI. Pretty sure XEs with EFI didn't have the TFI module for whatever reason. Share this post Link to post Share on other sites
