I broke it good. R.I.P. stock block.

Well I never got to raise the boost from 11# to 14#. The stock block gave up. They said 600 hp was the breaking point and we were all of that. You can remove the center 3 main webs by grasping the bearing caps, lol. The block cracked straight down from there to the cam bores and the cam bearings walked out and got whacked by the lobes. 11.34 @ 118 was her best. It still ran and drove onto the trailer. Never fear. I don't intend to go back on my promise to give us all a 10 secod pass. Dart is casting my new siamese bore 363 block, my custom grind Comp Cam just arrived, and Diamond is building me a set of custom dish pistons which they are sending to Scat to be balanced with my new crank and H-beam rods. I had an Eagle crank with I-beams before. Needless to say I am going to put a s--tload of boost to this one and maybe a little nitrous too (it cools hot blower air nicely). I intend to beat it mercilessly. 8-) Probably another month 'til it all comes together.

The 347 is dead. Long live the 363!

Glad to hear that you broke it good while having fun.

Update. I pulled the top end off and as I always heard it split the lifter valley the entire length front to back. Anybody got a 5 gallon pail of liquid steel?

Oh well, it lasted a good long while. My 9.65:1 347 will see 8/9psi eventually, hopefully turbo boost.

My 347 was 9.6:1. It's not just the boost or the power that breaks the block. It's in large part from the constant dragstrip launches. Imagine the load on the crank when you've got good power and traction and you're trying to get 4200# moving (me in it, rollbar, subframe, etc.). That is the single most stressful thing you can do.

LOL, do you mean like a 4500lbs SUV with A4WD, no tire spin and a 2800rpm TC? ;) I'm starting there NA, and when I build headers I'll see if it's feasible to make room under the AC/firewall area for two air pipes(turbo under the seat). Lots of people have put a remote turbo in a truck, but they all place their air filter under the truck, next to the ground. I'm not going to do that. Either I can route the air from a normal air cleaner under hood, or the turbo idea cannot work for me.

If my 347 survives my SUV for a while, I'll save to build a 363 for the truck(low compression and 15psi). Then the 347 will go in my Mark VII, and the turbo is simpler to do for that.

Did the rotating assembly survive with minimal damage? Might be interested if you would be willing to sell it for a decent price :twisted:

Don't know if the crank's straight yet. Everything's probably OK. But I've got my grandma's '83 T-bird with 30,000 orig. miles behind the shop. 6 cyl. base model. I think it wants to be gutted and get a nasty little NA 347.

It's my 98 Mountaineer, waiting for me to make time to work on it. I have Saleen bumpers and a wing to go on it, other interior parts, stereo, and different bigger calipers. I got hung up when I began rebuilding the trans, I have that in pieces now.

NO WAY!!! My Lincoln needs a budget 347 :lol:

sorry to hear the misfortune. i was keeping it under wraps, but im ditching my 331 for a 363 also. actually sending the heads and valve train out next week along with some other items, to be bolted to the shortblock being built by Jim over at Fordstrokers. hope to get the custom cam in by late july to be installed also. then 4week waiting period on the lower intake to be done, as quoted. hope to have it all back by late august if all goes right, and funds permit.

Say hello to Woody for me, he is the man when it comes to building Fords. Tell him I'll get mine in this year.
