The issues I am having with my transmission/clutch has sped up my plan to swap my current 440 to a 505 stroker I had built last year, or at least the short block. Here is the thread for the engine.

So far, things are coming apart very smoothly since its only been about 10 years since I bolted everything together. I will be dropping the K frame down from below vs pulling the motor/trans from the top which is a little bit of work but worth it in my opinion especially if you have worked with 2 inch TTI headers and a manual transmission, not fun.  I will be able to not disturb the a/c lines as I plan on suspending the compressor and hoses with a home made bracket while the engine is out. I will be doing the same for the front calipers so I dont have to bleed the brakes again.

I have the US car tool body lift that I will be using and will be posting pics when I get to that point.

What is up with the valley pan? Never saw one balloon up like that. Backfire maybe?

Will be watching as you take it apart to see if you can figure out what the clutch pedal problem was

Yes, I sure hope it is something obvious so I don't have these same issues again.  :cheers:

I wouldn't think a backfire could do that? My initial though was too much crankcase pressure.

Maybe I missed it,did you decide on the cam you were going to run?

MIGHT want to do a compression test before pulling out any more?!?!?

I had a valley pan do that when 3 or so pistons had the ring lands come out in multiple pieces. The stock cast pistons got rattled into pieces from detonation/preignition  :-[ The intake was probably the only thing keeping it from blowing all the way out

Hmm, maybe a clogged PCV valve?  :shruggy:  I will be replacing it on the new motor.

No decision on the cam yet, I will be calling to talk to either Hughes Engines or Dwayne Porter with my car and engine specs, but it will definitely be a hydraulic roller.

I may just for shits and giggles but this engine is going to be pulled and sold eventually.  I will be posting several pics of this engine when it comes apart, hopefully that will tell me more.  :cheers:
