    Looks like I have to order a new one. I was going to just order a Motorcraft. Unless there is something a little better out there?

    Crack in Water Pump

    The guy that bought the car from me in 2016 replaced the water pump for some reason. And a bunch of misc. parts. It was fine. He just replaced parts that didn't need to be replaced? Maybe he over torqued the bolts? Or defective water pump housing? Glad I caught it! Coolant spraying out under...

    Crack in Water Pump

    I was checking the car out for racing this Saturday and saw a small drop off coolant hanging on the battery cables that run under the engine. I found a crack in the water pump housing next to the bottom hose. Guess it wouldn't be a good idea to take it down the track like this. Looks like I...

    Mechanical Fuel Pump Block Off Plate Gasket Question

    There is little oil on the floor when the car sits for a while. I would like to replace the gasket. Can I do this without draining the oil first? Napa has the gasket. I would think it's correct. Even though they said it won't fit a 1993. I had to search 1985 to find it. What is the torque...

    These are the heads I was looking at. Well actually it's a complete kit. I think it's fairly priced. Good horsepower gains. But I'm not doing it this year.

    Need some advice on upgrading GT-40-X303 heads

    Oh boy I don't need frequent adjustment. I'm trying to stay as simple as possible! Looks like something more used in a race motor that gets freshened every 60 runs.

    Need some advice on upgrading GT-40-X303 heads

    (Head work is one of those things that it really just doesn't pay to mess with yourself.) That gives me my answer right there. I'm not screwing with the heads. I have no clue how to do any head work. I just talked to my mechanic, and he suggested a yearly leak down compression test. If and when...

    Need some advice on upgrading GT-40-X303 heads

    Thanks for the great information! If those heads had to come off, I would sell them. Then I would be putting the Trick Flow 11r top end kit on without a doubt lol! Thanks!

    Need some advice on upgrading GT-40-X303 heads

    Thanks ! So, no need for valve springs right? Now that I think of it, I contacted Alex Parts and I think they said the current valve springs are fine for the B cam. Heavier ones aren't required. Not planning on boosting it. I would really like to get the Trick Flow 11R top end kit. But at this...

    Need some advice on upgrading GT-40-X303 heads

    Thanks for the information. Yes, the heads have been in service for 15 years, but there is not many miles on them. It saw some street time. It's now an all out drag car on a trailer since 2020. Odometer doesn't work. There's probably only 30,000 miles on the engine.

    Need some advice on upgrading GT-40-X303 heads

    I've been racing this motor since 2007. I was thinking maybe the valve springs should be checked or upgraded to stronger ones. Also thinking of putting in roller rockers too. What ratio? I read somewhere you could pick up 10-15 rwhp? The heads are GT-40 M-6049-X303 heads on top of stock bottom...
