Ok another year and another race. Thanks to @318willrun for starting this fiasco with his 318 race and then the 2018 small block race.
Please remember this is for fun. If there are any problems with the system please refer those posts to 2020 small block race?
the purpose of this thead is for Sign Up's. Questions related to how many tenths to add/subtract are welcome here. We are trying out some new things. Strokers are allowed this year as well as the 1/8 mile racers. Strokers get a manditory time reduction and the 1/8 mile guys get a conversion factor to multiply or divide by. Hope that works out.
Race lasts from Jan. 1, 2020 to Dec. 31, 2020. This is for fun and there are no prizes. Please post a reply with your cars information and the additions/subtractions based off the penalty box. Once you go to the track and run you can post your time slips and we will put together a list of index to E.T. If you make changes to your car that will affect your index ie add aluminum heads instead of bone stock please post an updated index. As always have fun.

Penalty Box

Nominal Car (TDC) Tenths E.T.
LA 318-2 stock with 2.76 gears in a 3300 lb car (no driver) 100 % street at sea level (dual exh. ok) - 15.9

Weight 3300 lbs no driver. Add + / Subtract - .1 per 100lb (round to the nearest 100) always no driver.

Gear (2.45-2.99) = TDC (3.00-3.49) = -.3 (3.50-3.99) = -.5 (4.00-4.49) = -.7

Tires Height 25 inch - 28.5 inch =TDC 29 inch or more + .2 any D.O.T. tire OK

Vans/Trucks + .3 for wind resistance on any full size Van or Pickup (dakota/durango is NOT full size)

4x4 + .2 for 4x4's without loc-out hubs

Elevation
+.2 every 1000 ft. (use front numeral, no rounding) Do not figure air quality

Blocks/Cubic Inches
318 318 cubic inches is base (TDC)
273 +.6 for using a 273
340 -.5 for using a 340 block
360 -.6 for using a 360 block
Magnums subtract an extra -.3 from the C.I. section if you are using a magnum block

Engine Build (LA 318 2bbl is Base Engine)
Carb/intake -.4 be it a 4bbl, 6bbl, 2x4, FI, 360 2bbl, or anything other than factory 318 2bbl.

Exhaust -.4 for headers

Heads -.4 for worked 318 heads or stock 340/360/stock magnum heads
-.6 for worked 340/360/magnum heads (EQ's fit here)
-.8 for aluminum or W-2 type heads

Cam 318 2bbl cam is base (factory magnum cams fit here)
-.4 for ugraded cams of .480 lift/229 duration @50 or less
-.6 for upgraded cams .481 lift/230 duration @50 or more

Pistons -.4 for any overbore. Has to run pump gas of 93 octane or less to be street

Cranks 273 -340 Must be 3.31 factory stroke. 360 3.58.
-.5 for stroker cranks, this includes stock stroke crank in a block that did not use it from factory.

Tranny
904 904 is what is assumed in the TDC (nominal) car.
727 +.3 tenths for 727
OD/998/999 no penalty. Weight of O.D., and lock up with stock converters offset low 1st gear

Converter -.4 for upgraded street convert of 2200-2900 stall
-.7 for upgraded super street converter of 3000 stall or more

Valve body -.2 for manual valve body

Manual -.3 if you have a clutch

Clarifications
1) Car must be 100% street and remain that way at time trial. Street means pump gas, and cruising 1/2
hour at 55 mph on summer day is no problem. No open headers/slicks.
2) No power adders (boost/nitrous/high octane fuel)
3)Definition of "worked heads" mentioned, means milling over .010, any porting/gasketmatching or
larger valves.
4) Traction devices including DOT drag radials are ok. No Penalty
5) Hood scoops and fresh air are OK. No Penalty
6) Any ignition upgrades are OK. No Penalty
7) Honesty, just be honest. No purse, so keep your integrity
8) + is add. - is subtract
9)1/8 mile conversion factor is 1.5835
 
I'm in, why not. I make all kinds of passes throughout the year....
I'll enter 3 to start with.
  1. '74 Duster
  2. '76 Duster
  3. '89 Van
  • 74 Duster - 318, 4bbl, summit small cam, home ported heads, 904 w/stock converter 2.76, 3160 lbs, 14.6 ET chart index
  • '76 Duster - 360 w/360 heads, 4bbl, headers, small cam, 904 w/stock converter, 2.94, 3200 lbs 13.6 ET chart index
  • Van - Full size van, 360 magnum, 4bbl, cam, headers, 30" tires, Don't know the weight or gears yet, ? - ET

The calculation seems pretty accurate if I did it right. Now the only question/suggestion I have is my car can run on 93 octane and can run 65 mph on the highway in 90 deg heat forever. It cannot make a pass with 93 octane. So to keep the sharks out of the pool maybe the run must be made with 93 octane? Sorry Never mind, it already says pump gas run.

Is a A833 manual trans actually supposed to be +.3 not -.3?

I believe -.3. I think the reasoning behind that is if you had a 318 2bbl duster 904 2.76's, and I have the same car but mine is a 4 speed, with traction I can come out of the hole at 4k rpms and I'd beat you. Now, as the auto gets built, you see he has massive deductions for MVB's, good converters, etc. So, in the end the auto has more deductions. But starting with the nominal car, the 4 speed has the edge with traction. And I agree with the chart.

I have to kindly disagree sir. If you leave at 4k with a 318 2bbl and a peg leg 2.76 you are gonna put on a smoke show. Let’s add traction you say. Ok with sticky tires or even with a sure grip that turd is gonna bog all the way down to stall speed of the auto car at least. I feel there should be no penalty for a stick car, and yes mine is a 4 speed.

Respectively, I can tell you I've lined up Aspens, and other cars that were 318 2bbl stick cars against other 318 2bbl auto's in lighter cars, and the stick won easily. In fact, I've never had a automatic beat a stick when low horsepower cars are in stock form mechanically. Be it Ford Fairlanes, Dodge Daytona's, slant 6's, etc, etc. But it's Stephens race, whatever he decides :) P.S. - It won't bog down, because you don't dump the clutch. You ride the clutch a bit

On the four speed subject is there any consideration taken for the three times that the stick shift has to be shifted? The shifts are not as fast as an automatic unless you have a slick shift transmission which most don't especially if your driving it to the track.. generally a tenth is lost in between each shift.. also it's not as easy to ride the clutch in a perfect slip like setting up a torque converter for the perfect launch RPM...

You joining the race ? Cool !!!!! We sign up on this thread.... :) 4 speeds are faster in low horsepower machines. IF they aren't, it's the driver.
 
Only changes made to the chart over 2018 are
1. the stroker crank definition and deduction.
2. Conversion factor for 1/8 to 1/4 mile.
Posts have been up on the 2020 small block race?
thread for comment and feedback for several months.
Thank you for joining the race.
 
I come up with a 12.40 for my car with all the penalty deductions. I don't know what it weighs so there might be more.
I have never raced it but I would guess low 14's with the 245-60-15 BFG tires.
I'll try it this year for fun but I'm gonna get stomped by cars with 318's.
 
Alright, I'll play!

Hmm. Butt dyno says no way. I better get to tuning. Haha
Èdit : Fixed bad math. Butt dyno says no f-in way! But we'll give it hell!
This will be fun. I have several things I want add through the year I have laying around. Headers, cam, home ported heads, gears, etc.
