Projects update on the Model A Coupe

ok, I'll do that
but here it is, not all bolted down though, just one more dry fit.
now I can see exactly what all the misc nuts and bolts need to be like,
and I need to get another pilot bushing made before I can bolt the transmission up.
had to pull the old bushing, the Muncie input shaft didn't quite reach far enough.
but it's on the test stand, should be firing it up soon I hope..

 

THUMP THUMP, THUMP THUMP! That gold is the perfect 60's color! Hope you get a video and good luck with the start up! How much boost are you running with 8 1/2 compression?

 

That thing looks great.
The motor, the car, all of it...I like the gold, too, it was popular then, and it should have been. It looks great against all the "silvery" metals...great compliment to them.
What front axle are you using?
It looks like less than 4" of drop, but looks perfect, with the channel.

 

Nice looking engine.

What are you using to make up a pilot bushing.
Does brass work or must it be some type of special material?

 

M21 Muncie 4 speed for now..



and a '57 Olds rear with '60 posi pumpkin, 3.90 gears, Dutchman axles..

 

thanks Kathy,
don't remember exact boost numbers off the top of my head..
I'll have to find my notes..
it's slightly underdriven though...

 

triple belt woulda been cooler.

 

thanks, it's an axle I picked up a one of the local swap meets, dropped and drilled localy... I think it's a '35-'36 with about four inches total drop

bronze, specific alloy for this type of bearing

 

I can't seem to find my notes anywhere...

but if memory serves (and it rarely does),
the target boost was to be about six pounds...

 

rebuilt the carbs and got a new pilot bearing on the way..

 

I'm going to run the same Pont Olds rearend in one of my A coupes,do you have any photos of how you have it hung,or the width??
Thanks

 

oh, gawd yes!

 

Coming along nicely and it's going to be killer when its all buttoned up and you do that first smokey burnout. Of course we'll DEMAND a motion picture kinda thing when that happens.

that gold color is bad ass.....jeffrery ..perfect

 

Paul;
That is "Fan-freaking-tastic"
how does one-shot hold up on an engine?
FRITZ

 

MAN!! I want a blower!

 

this is the first time I've used it on an engine,
everything I've read sounds good though.

I guess we'll see.

The above chart shows the effective compression ratio of your engine, which combines the static compression ratio with the amount of supercharger boost. Note​

that for most street applications with 92 octane pump gas, you should keep your effective compression ratio below about 12.0:1

yesterday was baby steps,

got the pilot bearing from my machinist freind,
and bolted the transmission on for a test fit, looks good.

bolted the carbs to the adapter,
bent up some fuel line,
and drilled and tapped a piece of 3/8" stainless rod to tie them together

 

Lookin good!

 

Speechless.

 

first start after initial run in

 

Paul.Man that is sweet!! Ihad a friend in high school with a J-2 in a 31 roadster

 

tasty!

 

Paul I have used One shot on a motor and it held up just fine.

motor looks great. can i have a ride...

 

Looks good Paul. you gonna have that car done by the poker run this year?

 

Paul... How'd the 1shot hold up after the run in???

 

thanks,
maybe next year.. or the year after that, or at the rate this car is coming together who knows

 

what poker run?

I wanna go!

 

a little scorched around the exhaust ports as expected
