I just looked at the letter today. Looks like they are toast.

For what it is worth, the March 2014 issue of Hot Rod magazine details a procedure to check for an incorrect fit of the manifold to the heads. It starts on page 124 and is quite educational even though the engine in question is a big bock chevy. It is well worth the read.They used lead shotgun...

One of the reasons sprint car motors cost so much is that only the best parts are used. The sprint car guys around here ship their motors off to have them refreshed depending on the number of laps they run. At the end of the season they get a full rebuild. If you think about it you might run ok...

My thinking is that 70 p.s.i. would be adequate to get an idea of where your leak is. The one thing that concerns me is that you had a lobe go flat on your cam. If it occurred in a short period of time then it put a lot of metal into the engine. I think it would be a wise to take your oil filter...

Those non-wing guys can really put on a show. Separates the men from the boys. I have only been to one Nascar race at Phoenix and I would have to say that was one boring race. I much prefer dirt track racing over asphalt racing.

Now, after watching the Dave Blaney clip,imagine twenty-four of these cars on the racetrack at the same time going balls to the wall.

I haven't followed sprint car racing for a while, but I think the motor costs at that level start at $25K to $40K. They will be sent back to the builder after a certain number of laps for a refresh and get a total rebuild after each season.

Hydrazine has a rotten fish like odor too.

I can understand the frustration of having to go back and remove/replace a rebuilt part. I went thru this with a 95 Dakota,2.5l,starter that I bought from Autozone. I have big hands and am 66 years old. By the time I had replaced the second starter I was an unhappy camper. Rebuilt electrical...

I think I have that issue of Mopar Action talking about the power steering pumps. Thank you for jogging my memory.

Are you sure? It seems high to me. The reason I ask is that I am thinking of swapping a magnum engine into a 63 Studebaker and want to keep the stock power steering setup except for the pump. I also need to find out what the original Stude pump put out. It is the same pump as a Ford unit of...

Does anyone have any idea what the outlet pressure is on power steering pump off of a magnum engine?

I actually got the idea from a Studebaker parts dealer named Chuck's Studebaker Parts. Look under the special tools section on his website and you can view a picture of it as well as instructions in it's use.

I built my own by using the front hub off of a 68 Ford. I used it to remove the hub/drum off a Dana 44 Stude rear end. Simply drive out the bearing races,obtain a very large bolt and nut(inch and a quarter) and weld the nut to the hub. Turn down the face of the ford hub that fits against the...

Actually, in showroom stock condition, it might have been a good race. I do think that the Roadrunner would have edged out the GTO. This would have been especially true if they both ran an automatic.

Were their any problems with the AX15 holding up to the 5.7 hemi?

When you are finished be sure to back off the adjuster to zero otherwise the spring will take a set and affect it's accuracy.

The local rules say if it is "pump" gas it can be run and that is how they run the E-85 in their two barrel modifieds.

I don't know if you have raced before. If you have limited experience, just try to get reliable power and learn all you can about setting up the car. A lot of guys running the modified classes have been at it awhile and know most of the tricks. If they know you are new, most guys will be willing...

The local track runs a class called X-Mod which I think is similar to the B-Mod. They run a two barrel,cast iron intake, limited compression engine. I have a friend that builds Chevy motors for that class and he says the best motors put out about 425 horsepower. This might give you an idea of...

You might check over on the Moparchat circle track forum. There is a lot of good information there.

What outside diameter tubing will you use? You can get stainless tubing in many different wall thicknesses. Typical wall thickness ranges that we used in building our test systems ranged from .028 to .049. but it could go as high as .095. Annealed 304 stainless would might be a good option to use.

There were some people running 390's in circle track racing locally with some success in the 60's and early 70's but for the most part the big-block Chevy's were the first choice.

The 390 GT head had an exhaust valve diameter of 1.55 in. and intake valve of 2.02 in. diameter.

If that Cyclone is stock, I can guarantee that it will float the valves at about 4800 rpm and bend a pushrod. My buddy had one back in the late sixties and this was a common issue with the stock FE engine valve train.

I am curious about the weight of a 360 magnum with aluminum heads,intake,mini-starter and cast iron manifolds for an engine swap I am thinking about. My best guess is about 485 lbs. Is this close?

I sprayed some into a chevy distributor(window type) while it was running to dry it out. Bad idea. It blew the cap off the distributor.

If your heads have been angle milled it could cause a similar problem. Had this problem with a smallblock chevy circle track car where we were required to run a cast iron manifold.

We typically had all our torque wrenches on a six month calibration cycle in my previous job. The Snap-On Torqometer units are very accurate and well worth using. I am sure that most people are aware that the click type should be backed all the way off when not used because the spring will take...
