I'm halfway through installing a set on a 98 exploder 302 that I'm putting into my dad's car. It's got a TFS1 cam. since I haven't actually run the vehicle with them, I can't comment on the effectiveness, but from a materials standpoint and packaging standpoint I'm impressed. Everything is very well packaged and clearly labeled so that you don't mix up the intake & exhaust keepers, which locate the spring retainers at different heights for the intake and exhaust.
I do have to say though, that 2 things seemed a bit odd to me. The first is that these springs really don't feel as "stiff" as I thought they'd be. They don't feel much different than the stockers when I compress them with the tool. Maybe I'm just used to the double springs that I run on my LS motor, so these feel soft to me. The other thing was the valve stem seals. Again, maybe it's just because they're different than I'm used to, but these seemed to be a bit cheesy. But, as long as the springs and the seals do their job, that's what matters, but since the whole front end of his car is torn apart for a subframe replacement, it's going to be a while before I can report on how well they work.
Minor update: Last night I finished installing the springs. The kit included one extra intake keeper, and one extra exhaust keeper. Nice touch.
I've used them on two sets of gt40p heads. They are nice springs for the money. The last set I checked were all within a few lbs of each other at installed height. We ran them on a carbed engine with a 6500 rpm limiter without any signs of float.
I've got about 1500 miles on a set (just did a H/C/I swap, e303,explorer intake and Iron Gt40's) and they work awesome. Pretty much the same as everyone else...car bounces of the rev limiter like there is no tomorrow. Alex springs if my memory serves me right, also has more seat pressure than trick flows too. For the money they are worth their weight in gold
Hi guys, just sharing something I noticed working with the new style Ford hydraulic roller lifters (m-6500-r302 & r302h- I have both sets). On my 347 with GT40x heads, I could not get the new style lifters into the four corner lifter bores because these new lifters are taller and have less bevel...
93 gt with an f cam. When I start it cold the idle shoots up around 200 or so and idles fairly smooth then drops 1000 rpm. Then goes right back up. When it's warm it idles normal. Anybody have any ideas as to what I muted to check?
Looking for an F3ZE factory camshaft and according to this chart they could be found in '93 Thunderbird or Cougar 5.0's. However, it also shows the regular 5.0 HO cam in the '93 Tbird or Cougar. Is there a way to know which cam a '93 Thunderbird will have before tearing it out? I've...
Can anyone identify this 351W?
Numbered XE, odd grooves on block face,
Appears to have siamesed liners, .+030",
4 bolt mains
Piston valve cut outs appear to be for Cleveland heads (Boss 302?)
Rare? or just junk?
