I am starting to poke around for an RV. It will just be my wife and I traveling and staying in it. I will need it to tow my fully loaded 24' enclosed trailer (approx 10,000lbs). I really don't want something as big and expensive as a Super C. For those of you that are towing race trailers...

One of the bolt holes in my block (440) is stripped (one of the long ones in the middle). A couple of questions, can this be helicoiled, what size/pitch helical do I need. And most important, does the bolt hole go all the way through to the crank case, or is there a bottom to the hole? I don't...

In an effort to take some weight out of my car, I am considering switching to AGM batteries. I currently have 2 batteries wired in parallel and mounted in the trunk. Can the AGM batteries be wired in the same fashion? I think switching out the two batteries for 2 agm's may save quite a bit of...

My motor has been at the machine shop for months now. It has been one delay after another. Back in early August, I was told there was a 6-8 week delivery time for a set of Jesel shaft rockers. I stopped by the machine shop on Wednesday to try and get some kind of update. At this time, they...

I have installed a MSD 6AL Programmable unit in my car, replacing a standard MSD6AL. My distributor is locked and I dropped the dizzy in at 38* advanced with the rotor lined up to the #1 cylinder. broke out the laptop and created a curve that started at 25* (pulling 13* of timing) at 0 rpm and...

Not more than 1 month ago, I was at a point where I was consistently in the low to mid 10.40's. Since then, I have not made any changes to the car. This past weekend at Rockingham, I was struggling to get below 10.65 (with similar DA). The times were off consistently through the run from the...

I have wildwood disc brakes on all four corners of my 64 NSS car. The master cylinder is from a 90's Dakota. This set up worked fine since installed. However, now the fronts are dragging REALLY bad...I can hardly turn the hub by hand with the wheel off. Both sides are equally bad. If I...

I had been struggling with a slowly worsening issue with my car. It has been running like crap, very hard to start and would not idle. I could keep it running at idle, but would immediately die when I put it in gear. When it would start it would rev way up to about 3,500rpm and then die. I...

This weekend, I removed the choke plates on the dual eddy 1407's that I have on my 512 with indy 440-25 intake. Now the idle is extremely high....about 3000rpm. I have the idle screws back all the way out and the idle mixture screws closed all the way. The carb linkage is ok and the throttle...

To increase my compression a bit, and get a better handle on the internals of my engine, I am looking to replace my head gaskets. I have a 440 based 512 using a 440 source kit. I have searched but cannot find the proper bore size I should be looking for. I plan to go with a Cometic gasket...

I have a 7qt Charlies oil pan with an external pick up under my 440/512. There was a nagging leak coming from the pick up fittings so I decided to tackle that project today (instead of hanging out with the in-laws). Well one thing led to another and I ended up dropping the whole pan. Time...

What relationship exists between timing on the crank and phasing on an adjustable rotor? Here is my example, I am running 35* of timing (locked) on my 512. I have an adjustable rotor to assist with proper phasing. When the rotor is lined up with #1, it is moved approximately 7-8* off center...

The Rears on my car are starting to get a little tired (Ha!!!). I am looking at options for replacement. Current tires are Mickey Thompson ET Street 315/60/15 on a 10" wide rim. They are on my 64 Dodge 330 which is predominately a NSS race car (It does see some VERY LIMITED use on the...

The staff at the track are doing a great job documenting the process and progress of the renovations to the track on their facebook page. Daily updates with photos and explanations of the work being done. Very interesting to follow. Bradenton Motorsports Park

Great to see big investments being made to my home track! https://dragillustrated.com/facility-improvements-underway-at-bradenton-motorsports-park/

I pick up my car from the shop that installed the new rear end gears in my dana60. I now have a 4.30 gear on a spool in my 64 dodge NSS car. I asked the shop about break in and he gave me a procedure that will take a LONG time to get through given that this is a pretty dedicated race car...

I believe it is time to regear my car. Current set up is a 512cid, 727 trans with the PTC 8" converter. Crossram with dual eddy 1407's. Cam is a solid flat tappet 600/600 (don't have the rest of the specs handy). Running 30" tall drag radials. Current gear ratio is a 4.88. In the quarter I...

Block and tackles make it easy to move heavy loads through mechanical advantage. This can also be applied in reverse. Could there be an advantage gained by rigging a 1:2 ratio throttle cable? Normally, when a gas pedal is moved 1" it moves the throttle linkage 1". With a simple doubler...

How much of an impact does an increase in Temperature/humidity have on ET? Let's say my car can run and 11.20 @ 117 when it is 70 degrees out and low humidity (winter in FL), how much of a hit will I see when I run on a 90 degree high humidity day (summer in FL).

The cam in my 512 is a lunati that specifies lash of .026 intake and .028 exhaust. I spoke with tech support at Lunati and they confirmed that this is hot lash. knowing how much fun it is to work on a hot engine is there a fixed amount of adjustment from the recommended lash for setting on a...
