Well Im home today waiting for the new SB to arrive so I figured I'd get a head start on things. not bad for 2 hours of work. I bought the SB from Brian (dirtydogofthedesert)

SB Specs:

Engine is still a 9.1:1, same as my current motor



Pics of progress:

Good Luck with the swap Ron

Man, I thought you were still in some sort of "planning phase." I didn't know you were dead in the middle of this.. I guess this could still be the planning phase, planning to get another engine in! Looking good, bro!

What was wrong with the original build? Besides the builder?

 

[rford426]

Good Luck have fun!

Can't wait to see this run at the shootout later this month.

Good luck with it.

woah wasn't expecting this lol

 

[94tbird]

the builder was the problem and a noise that i couldnt identify or find and it wasnt easy to keep confidence in the motor. I figured id better do it now before soemthing bad went down and damaged the heads/cams ect

its also an excuse for the Billet oil pump gears lol

Don't like the rod side clearance or the crank thrust number.

Yep, thrust is tight and side clearance is loose. I didn't notice earlier, good eye.

 

[US-1]

You could drive a truck through the rod side clearance.

well the builder has tons of hi po engines and its better than larry h

 

[US-1]

My fuckin' dog can build one better than Larry_H.


Seriously.....the thrust clearance is way too tight. Should be .008-.011.

why is that a problem?

 

[US-1]

You do have a transbrake....right? Imagine what happens when the converter balloons slightly and pushes the crank forward and you don't have enough clearance. You end up welding the thrust bearing to the crankshaft.

 

[94tbird]

arent the anti balooning plates i nthe converter supposed to prevent that?

 

[Natural1]

Yes, but the thrust still has to be set properly. The recomended minimum clearance is .008" and I'd probably set it a bit loose.

EDIT: Recomended minimum is actually .005"

 

[94tbird]

ive been researcing since SDs comment and i keep coming up with 0.005 to 0.011 on msot sites. Not to say the internet is always right either, but whats done is done. cant be changed now

Wow. This thread is way over my head. But maybe I can learn something...

That campbell automotive spec sheet looks vaguely familiar.
