  1. I thought it was something more simple like a slightly different intake port location on the imported GT40 clone cylinder heads. I will add, I have tried many intakes on the 351W in my 69 Mach 1. The Edelbrock Performer RPM and Torker II both sat down lower than the Weiand Stealth that is currently installed. They all sealed just fine, but the fitment was a little different. In the end, of all that I tried the Weiand Stealth provides the best performance for a street driver. At least for my motor, trans, and rear axle combination.
  2. Before twisting of any kind. I think I would try adjusting the striker inward a little. Maybe that will get it close enough. Isn't the typical method, adjust the door to fit the quarter panel and rocker, then adjust the fender to fit the door?
  3. On Saginaw PS pumps there are pressure regulator shim kits available to adjust the pump output pressure. Is there something like that available for the Ford Thompson PS pumps?
  4. Like Barnett mentioned that is a common problem. I thought it was usually related to insufficient pump pressure. I guess it could be the hydraulic cylinder that is attached between the drivers side frame rail and steering center link. But, truthfully, the only issues I've seen with those hydraulic cylinders are leaks.
  5. I wonder if it has something to do with the fact that Weiand states this manifold also fits GT40 and TFS cylinder heads. I haven't seen that listed for the Edelbrock Performer intake.
  6. foothilltom seems to now have a combination that fits together. I wouldn't think there is anything wrong with the Weiand intake manifold.
  7. Great to hear some good news! You'll be happy with the Stealth intake. It works great on 351W motors. Plus it looks better than the Edelbrock Performer or Performer RPM. If you look on the bottom of that Stealth intake, I've noticed what looks like a small Buddy Bar logo. That intake has been around for a while. I wonder if Buddy Bar was involved in the design. Maybe somebody else here might have more information on that?
  8. The Weiand Stealth is a good manifold for street 351W motors. That's what I use. Plus it provides a little better hood clearance for an air cleaner than the Edelbrock Performer RPM. But, you better see if it will work with your cylinder heads.
  9. My 1969 351W has the original 1969 cast iron heads, but I use the Fel Pro 9333PT1 head gaskets. It is a Perma Torque head gasket and NOT one of their performance line of head gaskets. They are available at most parts stores or mail order from Jegs or Summit. I spoke to fel pro tech support before using them. What they told me was: (1) their performance line of head gaskets do indeed require retorquing after initial break in. And to retorque you must do the head bolts one at a time in the tightening pattern, loosen the bolt about 1/4 turn then pull back down to full torque. Without loosening you usually will not overcome static friction so the bolt will not be properly retorqued. As a Mechanical Engineer that is true, static friction is easily twice sliding friction. (2) The 9333PT1 is a Perma Torque head gasket that can still tolerate higher compression ratio motors up to about 12:1 static compression ratio. My static compression ratio is 10.7:1 so they recommended the 9333PT1 since I did not want to have to retorque head bolts. I would contact Fel Pro tech support and see if the 9333PT1 is suitable for aluminum heads as well. If it is, it's a fairly good gasket that's easy to get and less costly than some performance gaskets. https://www.felpro.com/contact-us.html
  10. Nice to hear some good news! Take your time reassembling the motor and new intake gaskets. Maybe take a look at Edelbrock's website for instructions and torque specs to install that manifold. Often with aftermarket manifolds the instructions will recommended to use something like Gaskacinch and literally glue the gaskets to the cylinder heads (but not the intake manifold side). Did you recoat the lifters with some assembly lube before reinstalling them? I don't know that it's needed, but might be a little extra insurance.
  11. Most are aware distributors advertised as Ready-To-Run mean they do not need any type of external ignition box or external ignition module. It doesn't mean the timing curve is optimized for your motor. An original distributor would be okay for a mild motor. But, be cautious of a used or rebuilt original distributor. The bushing and breaker plate usually wear out. Bushings are replaced on rebuilt distributors but not breaker plates. It's been a long time since I tinkered with stock ford points distributors, but I remember when the breaker plate wears, as the vacuum advance increases the timing, the dwell reduces. I've seen breaker plates worn to the point that the dwell reduces so much the motor starts misfiring when the vacuum advance starts increasing the timing.
  12. See the post I left in your other thread you started where you posted pictures of the intake manifold and cylinder head. At least by the pictures you can kind of tell what happened. Basically, it looks like wrong intake gaskets. At least that's what it looks like from the pictures. Hopefully there is nothing else odd.
  13. From the gasket imprint on your cylinder heads, it looks like the gasket wasn't covering the tops of the intake ports. Hence, the large vacuum leaks. And from the gasket imprint on the intake manifold, you had the wrong intake gaskets for the rectangular shaped water ports on the cylinder heads. Try the Fel Pro Performance or the Edelbrock intake gaskets I referred to on your other thread.
  14. Sounds like the issue is simply that the stock Felpro replacement intake gaskets that came in the gasket set didn't seal the intake manifold to the heads. With some luck no damage was done to the rest of the motor and a simple oil and filter change is all that is needed. Then I think I'd replace the intake gaskets with either the Edelbrock 7220, Fel Pro Performance 1250 or Fel Pro Performance steel core 1250S3 gaskets.
  15. What intake gaskets did you use? Stock replacement intake gaskets will sometimes not seal up aftermarket intakes. Since you have an Edelbrock intake, they have intake gaskets for it. They are almost identical to the Felpro Performance 1250 intake gaskets. Just a different color and I believe a slightly different material. For Felpro Performance intake gaskets, the most common one used is the 1250. Felpro also has a steel core version of the 1250, the 1250S3, which is a little thicker because of the steel core and also more durable.
