Chevy what? 69 GMC 348 SHOP TRUCK BUILD

[Tooth]

Today was a fun day! Mocked up the 348 stroker motor (409 THE HARD WAY) Jeff (Murphdog) washed and cleaned the block, installed cam bearings and degreed the comp hydraulic roller in. It was dead on!!! Then we installed the crank, rod and piston. Also put lighter springs on to check piston valve clearance. Found its needs cut .050 in intake valve area and widen radio's around valve .050 too. This will alow to be
Plenty of clearance. Exhaust valve is good... now pistons can be cut to finish balancing. Here's a few pics. I love this!!!!

Today the pistons were fly cut for intake valve clearance, .055 taken off. Now ready to start balancing process...

Looks good, you should soften the edge on the pocket cut in the piston.

Used fine sanding cone!

Softening done, pistons balanced, crank in the balancer. WAY better than I expected. But this is just the 2nd W I have balanced, the other was a 4" 409 in about 2007 or 8.

Well the balancing is finished, short block assembly next!

Is that the 348 engine you got from me?

 

[Iowa 409 Guy]

Lookin good. Is that the truck you're bringing to the Iowa race Tooth?

No, it's in my storage container. I got it from Tom K. Late 1961 block and I think he got it in Kansas City.

If I'm able to get it done and running in time...

 

[Iowa 409 Guy]

Need some help? Don't see any "Show Me" guys on the Iowa list.....easy money up there....

 

[Tom Kochtanek]

That 348 block was part of a bunch of W stuff I picked up in KC. It needed one sleeve as I recall. I think I gave $50 bucks for it. Has the ArmaSteel caps. Glad that I could infect Tooth with the venerable "W" and now look what he's accomplished with his two impending builds .

 

[Tom Kochtanek]

I am hoping we can get the BA409 car ready for both Ohio and for Iowa :

Might even be able to come out in the new "Donnie Shaffer" car hauler, who knows?

Well Murphdog called me and the Shop Truck stroker 409 MOTOR is balanced cleaned and ready to assemble. We'll be working on it this week.

409 shop truck short block assembled. Needs oil Pan and timing chain cover installed and painted. I wanted to paint the balancer first. Didn't need much heavy metal to get balancing dialed in. Went together super smooth. Oil pump, rod are ready too.
