I am ordering a custom sft cam from bullet soon. 275-288 @.050 .696-.674 lift, will be replacing a 264-268 @.050 Hughes cam which made plenty of power in my 470 just not enough cam for a drag race . I use edm direct oil lifters for flat tappet never had a failure and I run excessive spring pressure for valve control with a bigger 2.190 intake valve
Just ordered a Bullet Cam for my "306" 302 bored out thirty over. I'm excited! It had a basic stock cam for an automatic. I wanted a drivable/trackable spicy 5 speed. Gonna be a few weeks for them to grind it. TOTALLY STOKED! Project Stang! LOL
I have been buying Bullet cams for many years from Bullet cams. I was using them since the Ultradyne days. living in Australia you don't want to mess around with junk. you can make a simple jig that I made that allows the lifter to sit central and use a dial indicator to check for the lifter crown radii. if you have a mill bed or drill press bed its easier.
Got my first cam from Bullet over 2 years ago. 2 fast af engines later just received my 3rd for a new engine im building. Bullet is the way to go as far as im concerned!
Flat tappet cams have been having issues of going flat as the oils have changed. For cat converter life and better emissions for the environment bla bla bla. The zddp/zinc was lowered to about 800 ppm. From what I’ve read and followed the oil geek a flat tappet cam needs at least 1200ppm zddp/zinc to live. Some of the diesel oil 15w-40 and 20-50 oils have over 1200ppm but some still have too much detergent. A performance oil that specifically states high in zddp/zinc is your best bet. Yes there is also the question of manufacturing issues. Many have found that a major brand ( you said the name) are not grinding the crown on the lifters. Some have found the taper that’s required to spin the lifter while the engine is running. Hughes engines has a great article on what to do while installing the cam and checking everything. That major cam company has bought up a few of the other known cam companies. So has a major intake manifold company buying up the smaller companies. Good luck.

Interesting. Glad I built my 426 wedge back in 14. Hopefully when we break it in for the Charger, we have no issues. Thx for intel👍🏻

So I just checked. Bullet is in Olive Branch Mississippi, same town as…..wait for it….. Edelbrock!
So…do you think they work together? Just curious, I have a solid roller Bullet cam for my future ford fe, thanks 🙏
They grind all their lifters in house, in Mississippi.
Never got bad lifters or Cam's from Bullet / Ultradyne
Those are good cams. Nice choice. I would say the crap cam problems have been worse in the last 4 years.
