    TKO Driveshaft Yoke Strength and Fitment

    Got a fox body with an original Tremec TKO (3650), ford racing driveshaft, and a factory yoke from a newer model mustang (T45). I have the driveshaft off now and I noticed the yoke is twisted (I have a little over 500hp). I am trying to find a Chromoly / hardened yoke + U joint for this but one...

    lifting the heads under boost? air + oil in coolant

    basically stock 5.0 with an on3 kit MPT70 turbo, 9psi, a little over 500hp.. A while ago I noticed my overflow bottle was brown. Found out its oil... sweet. Another time, I noticed the overflow was bubbling, almost like a boil. This means a bunch of air is being released by the cap, so air...

    I have an 86 shortblock with E7 heads and a MPT70 pushing 9 lbs, completely stock otherwise. Right off the bat I had issues detonating and blowing out spark. We brought back the timing a little and I went with Autolite 23 plugs gapped at .028" and a MSD coil. I then continued to make 420rwhp...

    FL910 oil filter?

    Anybody heard of using a FL910 oil filter on a 302? I have a turbo setup on my '86, and I can't run the FL1A. I was browsing through oil filters and I came across the FL910 which is for the escape. Its tiny, but has the same thread and same seal as the FL1A. Clears my turbo manifold perfectly. I...

    which draglites to get?

    I want to get a set of draglites for my '86 GT daily driver. The whole sizing / backspacing numbers always confuse me so i'll just ask. I have the stock quadshocks in the back, should i still go with the 15x8 in the back? Also, what backspacing? I'm going to run a smaller street tire like a...
