Angry popped a valve spring today

Took the Mustang out for it's first drive with the new engine, IT'S SO FAST!!!!! 0 to 60 is instant. I didn't get real crazy with it though, never went over 4k rpm. Drive it up and down the road twice and on the way back the second time I started feeling a misfire. Decided it was probably a mechanical issue due to it's abruptness. So I loaded it onto the trailer and brought it home. Pulled the plugs, # 3 didn't look like the others. Decided to do a compression test starting at #1 and heading down the line. Got to # 3 and we had nothing. F. Pulled the valve cover and discovered a broken valve spring on the intake side. By this time I was expecting the worst, a hole in my piston, bent valve, ect. I took the rockers off and my dad pulled the valve up while I turned the engine over. Luckily it had great compression. So, I've emailed TEA for a replacement. Could've been a lot worse.

^ That would be nice but I doubt it. I bought these from a guy over on Corral. I don't have a part # so I'm hoping they can help me out. They are LS1 springs, 1.300" diameter with 160lbs on the seat and 440 at .600 lift

you really should give ED at flowtech an email and have him set you up with some springs that won't do that, I'd be leary of the rest of them.

^^^^^^^^^^^^^^^^He's right on the money^^^^^^^^^^^^^^^^^^^^^^^^^^^
I wouldn't even be sleeping until I had all 16 springs off that engine and correct ones installed.
Don't forget to use all new locks also.......

I don't plan on replacing them just yet. When I ordered my cam I sent all of the information on my setup to Jim. This was a fluke most likely. I'll just see what TEA has to say and go from there. Now, if another one breaks, please believe they're gonna be gone.

replace them now before another one breaks... before one of your pistons decides to introduce itself to a valve
