Sorry to hear about your motor. But I guess 30K on an OEM short with 465 at the wheels really isn't too bad!
Good luck with the build!
Good luck with the build!
Finally get my own "KABOOM" thread!

Agreed.
I feel the car was higher than 465hp for the last 10k miles, but hard to tell for sure.

1/10/14 UPDATE:
CRANKSHAFT
Forged Cobra crank came in the mail. First piece of the "new motor," so I'm pretty excited! I will drop it off to get turned/polished on Monday. Minor scouring, the worst of which is pictured below. I don't feel it's anything to worry about. I can't really feel the grooves with my fingernail, so I'm sure polishing .010" under will be adequate.
PISTONS
I wasn't sure on compression ratio desired, but I've decided on low-mid 9s. With 91 gas and ~15psi boost, I think the 11cc dish pistons will be good. I ordered them today, and they should be here next Wednesday or Thursday.
I went with Manley Platinum series in a 2618 alloy, plasma-moly rings, bored .020" over to match the block.....
BLOCK
...which I will be getting either Sunday (if they guy meets my friend half way at the track), or Tuesday (I have the day off and will drive 3hrs to meet him). It's the FRPP Aluminator block. I've seen pics only so far, but it looks good and is supposed to be "ready to go" already bored out .020". I will have my shop look over it to make sure nothing was messed up. "Trust but verify."
RODS
I snatched up some young Manley rods from an 03 Cobra (only 20k miles at 450 whp). They should be here Tuesday or Wednesday.
CLUTCH / FLYWHEEL
I got a SMOKIN deal on clutch and flywheel. I currently have a Spec 3+ 10spline clutch and 6 bolt Spec aluminum flywheel. I am now using an 8 bolt flywheel and 26spline input shaft (once I beef up my 3650). I was not looking forward to having to buy new versions of the same clutch ($490 for the clutch and $320 for the flywheel), but I found a guy selling a Spec 3+ 26spline clutch and Spec 8 bolt billet steel flywheel, and I got them for $150 shipped. Less than 5k miles on them! Saved a lot of money on that one (which went entirely towards those pistons)
========================================================
I've borrowed my girlfriend's DSLR camera for the build/progress, so I should have quality photos. I'll try to be intuitive throughout the build thread, but definitely let me know if you have suggestions or questions! This thread is for discussion (and to keep me busy between working on the car -- waiting on machining and whatnot).
Brother's Catalina STILL isn't back together. I got home tonight after a week of traveling, expecting more, but I guess he's been too busy with school. Family is in town this weekend, so I'm not expecting to make much progress until Monday.
Thanks for reading!

Sounding good! Did not that clutch and flywheel end up working out or did you find another one?

I found those aftermarket Spec ones, and decided to go that route instead of stock Cobra components. I've had good luck with mine so far, and the spec stage 3+ is rated for 850ft-lb, which should be enough for now. Lol

Engine is almost in the brother's car. Hopefully my engine will be out by next weekend.
It's a 455 with a triple duce carb. Sounds really good when the secondaries open up!

Did he do a rebuild on it?

Yep. He had some rod bearings go out. He just turned 17, and Dad thought it would be good for him to learn, so they tore it completely down and rebuilt it.
That was the fast part.
Putting it in the car and hooking it all up is always the most tedious part. (Part of the reason I want to get started already...)

Nice. I sure wouldn't mind having a catalina some day. You don't see a lot of them out there.

That's the truth. Most people don't know what one is. It's always fun having something less common.

Received photos of the block. Good chance I'll get it tomorrow.
I think it looks great. Pretty excited about it!

1/13/14 UPDATE:
Received the block. All looks good, and it's on its way to the machine shop to be looked over again.
Steel caps, instead of cast. Should help with strength.
Is this nick anything to worry about? I think it can be cleaned up, but not sure.
Anyone get anything out of these numbers? I'm assuming "August 31, 1998"

I ran into something weird:
06 GT specs list 2.0867" for the rod journal diameter, and 03 Cobra specs list 2.2388" for connecting rod journal diameter. I have a '96 cobra crank that measures 2.086", so the larger diameter worried me for a bit.
After some discussion, we came to the conclusion that the difference (approx .15", or a tad more than 1/8th inch .... i.e. 1/16th all the way around) was the rod bearing thickness, although I couldn't find the thickness listed anywhere on the rod bearings. We assumed that 2.0867" was OD of the crank and 2.2388" was the ID of the connecting rod.
It makes sense to me, but it's still just a guess until I get the rods (Wednesday). Does anyone have a 2003 Cobra crank laying around, and can measure the rod journals?!
Thoughts/discussion?

All cobra cranks from 96-04 are the same
All modular cranks including coyote have the same rod journal size.

That knick in the cylinder looks like it's high enough to not be a issue.

I was really hoping so. As long as the top piston ring doesn't reach there, I won't have any blow-by... and it doesn't look like it will interfere with the head gasket.
Correct?
Also, FedEx just came by!
Pistons will be here tomorrow.
