Save my 409

[Jeff Sine]

After disassembling my 409/425 and doing a initial inspection at the machine shop. I'm hoping to save my 409!
A scored crank, a spun #1 main bearing I'm waiting to hear from the machine shop to hear if the block can be saved. I'm hoping to find a rotating assembly if the news is positive.
Any sources for parts suggested?

Show Cars is a really good bet,Jeff.

Welcome to 348/409 Jeff. Many intelligent engine builders and cranky old farts here. Hope you hang around and post pictures of your ride.

If the 409 main bore can not be saved look into going to big block chevy size on the mains.
Just may save the block.
Now this will take crank work to pull it off but not that far out of reach.

La Hot Rods, Are telling me that Big Block Main Bearings and turning down a new crank is a viable option?

BBC crank only needs the counter weights and the snout cut to size. Eagle and maybe Scat offer drop in stroker cranks. Show-Cars has a selection of stroker kits.

The main bearings on a big block is 2.748 as to a 409 being 2 498.
So you could have the main enlarged to the big block size.

Ok this is the route my machine shop will go. He will not go with modifying the BBC crank. He will install a Scat or Eagle rotating assembly and is going to Bore the cylinders .030 over and fine cut the deck the minimum. The Block has had a cylinder sleeved and Oil feed restriction modifications to reduce oil supply to the top end which will be returned to stock. Evidently this old girl was used for Racing!

So thy could save your main bores?

Sounds like you're going to be OK, and 30 over sounds good.

Nice looking "64" you have there. Honduras Maroon Metallic is one of my favorite colors. Don't see many around. Have more pics and some history of your car Jeff?

 

[Jeff Sine]

La Hot Rods,
Yes, we are going to save the the Block. The machine shop is going to take a minimum cut off the main caps were they meet the bock which changes the bore center and then when boring the mains it will cut the damaged area from the Block. A Timing Chain that is made for this procedure is all that is needed from what I have been told.

Iowa 409 Guy,
Thanks for the compliments on the car. Here are some Pics.
If you are interested click on the About tab on my profile to see my story with the 64.

 

[Iowa 409 Guy]

Not seeing the About tab. When I click on your name I see your age and where you live???

 

[Jeff Sine]

When you click on the pic and the next window pops up click on my name and then the next window the ABOUT is in the blue bar.

 

[Iowa 409 Guy]

Cool story. Thanks for the tip on the about tab. I had not found that since the update.

 

[Don Jacks]

Jeff,on your timing chain,Show Cars has them in booth-.005 and -.010 just for blocks such as yours that have been line bored.

 

[Jeff Olson]

[Jeff Sine]

Thanks Jeff,
I'm finding this very informative and Fun.

Starting the cleaning and painting of parts while waiting on the Machine Shop.
Used Eastwoods fast etch rust remover and High Temp paint on the Exhaust manifolds.
Hoping it holds up but not expecting much more than the break in running.
Anyone been down this road?

I have used their Hi temp coating in a pint can and it lasted for years
