    Rebuild #4...

    Oh boy, I have never bought engine parts on Ebay... :eek: I guess I will have to get used to it... Although I do like the idea of searching Ford dealers for these parts. I want the latest revision of parts. Over the years Ford has revised a lot of parts since the last S197 rolled off the line...

    Rebuild #4...

    Its been a while since I've been here... Well, I'm at it again....4th time. My short block and heads are back at the machine shop getting evaluated... sigh Had a mishap with PAC Springs being too stiff and destroying a rocker and cam lobe... I replaced the springs, cams, rockers, followers...

    Whats the story behind failing cam follwers...?

    Actually, they revised them after 2015 again... I believe the current version being sold is only a few years old (less than 5).

    Whats the story behind failing cam follwers...?

    Update, spoke with a couple of builders and tuners. My current setup uses PAC 3V Springs that have an open pressure of 270 lbs. That's a stiff spring. The recommendation is to go with a lighter spring; Comp Cams 26113-24 which have an open pressure of 198 lbs...significantly less. I will lower...

    Whats the story behind failing cam follwers...?

    I did read that. And I was wondering why the F150 3V had that issue and not the Mustang 3Vs... What is the difference in valve train? The new followers I just picked up from Ford do have a much smaller hole!! The original OEM followers from my stock engine had much larger holes, I believe they...

    Whats the story behind failing cam follwers...?

    Yes, this has happened previously, but I caught it in time before cam damage occurred. I have found numerous followers where the bearing roll rough and gritty. I have previously and recently found rollers that have seized and were flat spotted due to the cam lobe. So the initial failure mode...

    Whats the story behind failing cam follwers...?

    I've experienced catastrophic valve train failure due to failing cam follwers (rollers / arms); both driver and passenger side. Has anyone else experienced this? Did you ever figure out the cause? My followers are failing in just a few thousand miles; less than 10K I believe. The rollers end up...

    MSD 8740 Mustang COP Current Booster

    Justin is hard to get in touch with these days. Since I'm back I've wanted him to tune my car, but seems like he doesn't tune anymore. Now it's another guy... and they need the car a few days. What happened to 2-3 hour tunes as you wait?

    MSD 8740 Mustang COP Current Booster

    I run NGKs Iridium (7554) gapped at 0.025. Never heard of side gapping. Just researched it... very interesting. That's where all those funky 90s plug designs came from. Lol

    Higher boost will need a stronger spark to jump the gap. You reduce gap to facilitate the spark jumping to the electrode as the coils do not have enough energy to jump a large gap under boost.. Basically reducing gap concentrates the spark... less air to travel through.

    MSD 8740 Mustang COP Current Booster

    Skwerl, you're back!!?? What are you driving these days? I'm back in Central Florida as of late last year. What I'm trying to accomplish is a stronger spark with a reasonable gap. Right now, the gap is tiny... And its forcing me to R&R plugs more frequently than I care to do. In my...

    MSD 8740 Mustang COP Current Booster

    That has been my experience too... I tell everyone to stay away from aftermarket coils. OEM is rock solid... it's used on 1500hp motors. If it works for them, good enough for me. Lol Since this is a different method than replacing coils, figured I'd try it... Somebody has to test the new...

    Nope, not running that feature... Just want the increased spark.

    MSD 8740 Mustang COP Current Booster

    When I was in search of bigger spark, I ran through the aftermarket COP issues that comes with boost. I tried all COPs at the time. Long story short, at least with the MSD COPs, it has much larger coils that require more amperage to deliver the necessary spark in boosted applications. At least...
