Technical ***September 2020 Banger Meet Thread - Four Months of 2020 to go***

Haha, actually pretty light at 531 grams.

7.5 to 1 with my T block, A crank and rods, and Fronty head.
My wallet is empty, I feel like I just shook it upside-down going down the road. Can't wait to get the bill for the engine work. I'm sure it'll be worth it though.

Have the three carb finned intake manifold part number is A-945-tpl USA made for $235.00

Chad,

That is very good, mine are about 570 but have no dome. They are a little thicker deck thickness, built around 13:1 CR.
I am sure it will all be worth it in the end, keep at it, John

 

Hey Fellas
Haven't signed in in a couple years. Life, work etc...
Anyway nice to be back. Still have my cars they just don't get driven as much

 

Ordered one up, hopefully I won’t get an email next week saying they are no longer available. Thank you for the help!

 

If your wallet is empty you need to find an additional job for your wife.

Welcome back....always liked your signature

 

Love it, my dad drove truck recognized it right off.

 

OK finally getting close. standard bore diamond B block with the bigger intake valves, winfield grind cam, Simmons power head, dual 81's and a Mallory distributor...... what spark plugs

 

don't know the short answer don't even know the spark plug hole size

Spark Plug Heat Ranges:
The following list of 7/8-18 inch spark plugs fit the original Model A head. However, the results of the use of some of them could be detrimental to your engine or at the very least, foul out. In other words, just because a plug has the correct thread and length to screw into your Model A head does not mean it is the one you should use.

A heat range test (discussed below) is the best way to determine the correct spark plug for a particular engine setup and a person’s driving habits. Champion plugs appear to be the brand most frequently used but that does not detract from the quality results of other brands.

Champion recommends the W-18 to be the modern replacement for the 3X as their heat ranges are fairly close.

Concerning the W16Y, according to Champion, the W16Y, being a projected nose plug, is hotter than the W18 or even a W20 at low speed but cooler at high speeds over 5500 RPM, which according to Champion, the high RPM is necessary to cool the projected nose with a rush of incoming cooler air even though there is greater combustion. Obviously, such high RPM will never apply to most Model A’ers. Regardless, however, most people report that the W16Y runs cooler than the W18 at ANY speed in a Model A.

The performance of the W16Y in a Model A, as compared to Champion’s general description of its performance as a projected nose plug, appears to be an area of controversy for some Model A’ers. However, the Champion 7/8 plugs, including the W16Y, fit a variety of industrial and agricultural engines that run under all kinds of running conditions and loads and obviously Champion does not feel the need to make statements about how the W16Y specifically performs in many Model A’s.

Consequently, if some Model A’ers make blanket statements based on the results of the W16Y’s cooler performance in many Model A’s it should be considered inaccurate as a blanket statement because the W16Y may not perform the same in other engine brands as well as some Model A’s. Plus, the results of Champion’s work would no doubt be determined under controlled conditions where the air/fuel ratio, spark intensity, etc., would be near perfect which is not the case for most Model A’s.

So it's still best to use the following list as a general guide, but also do your own heat range tests and reach your own conclusions and opinions when running any of these plugs in a Model A engine.


Champion (hotter down to colder):

W89D
W16Y (For Model A engines it ought to be somewhere between W18 and W14)
W20
W18 (About equal to the original 3X per Champion)
W14
W10

Also the original 3X which Champion lists as normal along with the W18.


Motorcraft (hotter down to colder):

TT15 (the same as Champion W89D)
TT10 (the same as Champion W14)
TT8 (the same as Champion W14)
TT4 (the same as Champion W10)


Autolite:

3076 (the same as Champion W14 and Motorcraft TT10)


Mopar (hotter down to colder):

P-9-7S
P-9-6S
P-9-5S


Prestolite (hotter down to colder):

78-10
78-8


Stitt (hotter down to colder):

137 BSP
197
147 B
13/10

i run NGK plugs

 

Northwood IA 2020 hill climb. Gary

 

Guess I will run the 3X since I have them and see how the work out. Thanks

 

It finally runs. .030 29 block. D4b Thomas style head. Equalizer dual intake. 2 stromberg 81’s. Reds header. SOS front cover and pulley. VW points distributor.

 

Good looking car...is that why the Vdub is parked, you need a dizzy for it?

 

Nope - That is the Daughters graduation present. It runs great!

 

Got my new FSI distributor in the mail today, looking forward to installing it.

 

Vw's and model A's?

 

What is the torque in a hot flathead banger? 30lb?

 

As in engine output torque?? my car was just on a chassis dyno and got 141 foot pounds of torque. Winfield redhead dual 81, 226 inch stroker

Dang that's great numbers!wonder what stock output is .ive heard 40 horse but nothing on torque

 

i would think more like 45 # ............. mine are @ 55 - 60 ##

 

Anyone have a stock Model A oil pan dip tray they want to give up and ship to me? Need to build a setup for my A crank T engine.

 

There's a guy selling two A engines near Ashland Ohio for $200. They would be good parts engines... one was converted to an air compressor. https://www.facebook.com/marketplace/item/554851285233853/

That's a good price, but I don't have any use for an entire engine, I just need the dip tray in the oil pan.....plus that's pretty far away.

I shouldn't post during happy hour LOL

I am looking for the amount to torque the piston rod nuts. I guess the mains as well.
