I always rotated my Hoosier 9" Lightweight radial slicks after every weekend. Pretty much eliminated uneven wear, longer life till the wear holes started disappearing and gave me a chance to check rear drum brake adjustment among other things. I don't know if tire type. air pressure or...

NHRARacer.com - NHRA RULES NHRA rule book General Regulations Section 21 Page 46 It says: SNELL 2015 expires 1/1/2027 SNELL 2020 expires 1/1/2032 I won't be the best source for some rules. I retired from racing a few years ago and haven't been keeping up with the rules like I use to.

The motor plate should be no less than 1/4" aluminum. Not sure about the thickness of a steel plate but it would be stronger than aluminum. MUST HAVE limiters to keep the engine/trans from moving back & forth on acceleration & braking. Trans mount in good shape? Might be better to go poly but...

KB (hypereutectic) pistons require wider than normal ring end gaps. Perhaps that one was a bit on the tight side or running hotter than the others and butted long enough to break. Perhaps some pre-ignition, detonation? Broke on installation? No cylinder wall scuffing is interesting.

Anytime you change the "size" of anything (i.e.: cam, carb, headers, intake plenum, etc.) it can affect the optimum calibration of the carb. Bigger stuff tends to reduce the vacuum signal to the carb so you may need to provide a longer accellerator pump shot and/or bigger squirters and/or more...

Was there any clearancing done for valve spring/retainer clearance? It also wouldn't hurt to check the valve springs for proper pressures. Valve float can produce loads well over normal operating conditions.

Actually, when humidity goes up, you need to jet down (go leaner). The reason being is that higher humidity means there are more water molecules in the air which displace oxygen molecules. Water doesn't burn and with less oxygen available, you need less fuel to maintain an optimum A/F (air/fuel)...

6 cylinder torsion bars have always worked well for drag racing. Naturally, lower mileage and rust free units are preferred. Modern suspension technology has also reduced the need for fastest weight transfer and greatest suspension separation.

"B" - I always balanced my slicks and while they usually did move a bit on the rim (no screws), I swapped them side-to-side after every race weekend so they would move back a bit! Rear brake adjustment was also checked while swapping. It wouldn't hurt to check the balance after a while but I...

No comparison between 2.45 and 2.74, but everything I heard or read about 2.74 low pointed towards benefits in heavier and lower torque applications. In my case it was in my 3,540+ lb 360 Dart with 4.86 gears and 30" tall tires. It helped it to a best of 1.47 60' times. NHRA class Stockers can...

6,000lb axles and 16" tires is the way to go in the long run. Best to have more capacity than you end up using. I also agree with more length than you think you need. 26-28' should cover your needs. It did mine when I was doing a lot of traveling and it served as a well equipped garage as well...

FWIW, I had my extra converters matched after i found performance that I liked. The original converter "rating" was "4400", but they actually flash to 4,900 - 5,400 in my 360 Dart Sport combo, mostly depending on heat and humidity. On the line my footbrake held to around 3,000, but that depends...

Just something to consider - Naturally a lighter car should be a faster car. It can be a personal challenge/goal or it can be a necessity to simply out-run an opponent. However, in some cases, it can be beneficial to keep some weight by putting it where it will do the most good - towards the...

Does your car weight include a 6-8 point roll bar and/or frame connectors? I can't tell by the photo. Going to a 904 will save a few pounds overall plus pick up about .15 in the 1/4 mile due to less reciprocating weight if converter specs are the same as the 727.

Did you put a Cal-Trac or similar system on or just split mono-leafs?

2017 was the last year IHRA had Stock Eliminator or any other classes similar to NHRA (i.e.: Super Stock, 3 different .90 classes, etc.) An NHRA rule book and research on their site will answer most questions. Then it will be easier to answer any remaining questions. ClassRacer.com forum is a...

Thanks, but I ran IHRA Stock since 1999 & tried to get into NHRA Stock (Under index & dial-in). Ran index a couple of times at a local track, but not my cup of tea.

I've been at races where I didn't seem to sweat much despite the heat. But if the humidity is low enough, your sweat evaporates before it soaks your clothes. Drink often because if you get thirsty, it's too late, you're already dehydrating! I always brought a huge cooler for food and drinks...

Praying for a thorough recovery.

To elaborate on what 67Dart273 said, in my experience, with the passenger side squatting and/or the driver side raising is an indication of the leaf springs wearing out. The process is slow and not readily noticeable, but may require a front shock/suspension adjustment to help it leave...

I have a Pioneer CA-8417. Probably a V-8 application and it's what I have on my 360 Dart Sport with a Strip Dominator intake, 1" spacer & Holley carb on one of the factory throttle cable brackets. It's about 19" long overall and has about 2 1/2" of travel. If I remember correctly, there is...

For a small block, I fabricated my own. Took some trial-&-error, but lots of angles to consider. Not as much in belt options or adjustability as it turned out, but it works. It was hard to clear the radiator hose.

Jets for MPH and pump cams & squirters for 60' & 330'. But you'll have to go back & forth to fine tune it. Ideally you want the squirters to stop squirting simultaneously when the primary jets kick in (on a double pumper). I also found a little benefit to jet the deeper side of the plenum on a...

IMO, a steel billet yoke using Spicer solid u-joints are the way to go, whether it be an 8 3/4", Dana 60 or anything else. The ring & pinion then the carrier caps are the next weak links on an 8 3/4". OEM driveshaft is in the mix, but you likely need another one anyway so an aftermarket version...

Chances are very good that the trans (sprag) is hurt since it broke under load. Several years ago I was at a double-header points race. Stripped the ring & pinion on a T&T run the day before. Because of points, I took a chance & swapped in a new center section and won the next day...

Handling mods like you have are on the opposite end of the spectrum when compared to drag racing. Leaning one way compromises the effectiveness in the other. Not only do sway bars limit weight transfer, the torsion bars do too. Thinner bars actually store energy because they are twisted more and...

A body has all the advantages. Lighter (Better results with building a small block.), shorter wheelbase (Better weight transfer/traction.), probably easier to get parts (body & chassis) for and you already have your experience with them. Biggest disadvantage I can think of is the '72 & earlier...
