How did that happen?

 

WoW i have seen a lot and let me tell you that is one of the best, or the worst depending how you look at it.

 

holy **** what the hell happened?

 

How many R's did it take to do this?

 

i had a small oil leak i "thought" i fixed but also cuz i like to really drive my car. i really dont mind it breaking except for the price to fix it cuz i like to work on it. i threw 4 rods and burned up a crank journal. now im going to build a 383 stroker with the block . ............by the way whats an "R"?

 

R's is RPM's. Make sure you use ARP rod bolts on the 383.

 

oh the rpms werent high at all i was driving home going 70 in overdrive so i guess that makes the rpm's around 2500-3000 rpm

 

Make sure you get that block check out by a very competent machine shop or engine builder. With the damage to the rest of the rotating assembly I wouldn't be surprised if the block has some damage as well. It smoked a rod journal or main journal? Not trying to make your situation any worse, just telling you what I think.

 

Throw that block away 2bolt mains arnt worth much for perfomance. Go find a nice 4bolt main so it can handle over 400 hp reliably.

 

2 bolt blocks have seen 500 horse without breakage,

2 bolts will hold 450 in its sleep..

u should have the block gone through thoroughly

 

Wow. Very nice. This gives you a nice excuse to build a new motor. I would say this was spinning at 7-8K or you ran out of oil...

 

WOW!

 

this is the only damage the block got is the block still good?

 

heres a piston

 

So you want to make a 383 out of that block. I'd strongly suggest another block. The longer stroke of a 383 will bring the piston even closer to that damaged area.

 

I agree with rick and toss that scrap iron away. I wouldn't chance building a new motor on that block. And just to chime in...I've seen a two-bolt make 650 flywheel horse and run all day long. Much more and you do need a four bolt or have the machine shop install splayed four bolt caps on your two bolt block. especially since two bolts are a dime a dozen. Just my $.02.

The fact that the rods let go like that, and that rods letting go are the most common failure mechanism are all the evidence a laymen should need to realize that the main caps are generally not the weak spot in a street 4" bore SBC.

 

exactly the point I was trying to make. Just please make sure you get some good rods and arp bolts.

That is impressive!

How'd the car act when she locked up?

Throw the *** end around?

 

naw it just died and started rolling

 

Man, I have seen this to often. As far as stroking that block, I would forget about that. However if you ever wanted to rebuild it as a 350 again, I would take it to a machinist and have him clean and mag it. Unless you clean it and see any cracks off the bat. I have seen a few times where when the engine throws or two it leaves obvious or hairline cracks in the cylinders walls.
Good luck with a rebuild!

 

get a two bolt block with splayed caps, they are stonger than the 4-bolts. 4-bolt blocks are over-rated... but I still had to have one for myself :-D lol
