It had hypereutectic pistons, i guess they couldnt cope?
It was #3 piston.

This was in the intake...

iTrader: (6)

Oh man, that's ugly!
So the piston is in a million little pieces throughout the engine?

Do you think it might have dropped a valve first? Were you racing?

So what is plan B?

Mr.Wolf

iTrader: (1)

yikes,

ZONES89RS

iTrader: (2)

Yea, the conclusion is a dropped valve, pieces are EVERY where possible, i pulled the intake and was like WTF?

Plan B is using my old 357 to get her back on the road with the vortec heads and a LT4 hot cam or a ZZ4 cam, ither one, i hope to use the LT4 but i have to get some work dont i think for the heads to allow for the lift.

Mr.Wolf

iTrader: (1)

that sucks man,

esc

iTrader: (6)

I used to run a 357...it was a mean piece of hardware. I can't even count the number of mustangs I put in their place back in the 80's with that motor.

So what will the heads need for the LT4? I'm not real familiar with either cam. It is a spring issue? I just spent most of the day changing the springs on my car.

ZONES89RS

iTrader: (2)

Well, the springs on my vortecs are good for a .490 lift, with the LT4 cam dawn from 525 lift with 1.6 rockers to 1.5s it is .492 lift, so i have to have the heads checked and see if they will work and see if they will even handle hydrolic roller, i had a 497 flat tappet on them before.

Was it you that was saying in a different thread that you do your own machine work? I think I remember reading that... If so... sweet, so you work for a machine shop or are just ridiculously rich & have that stuff in your garage for the fun of it? Anyway, I have a Vortec 350 I got off the guy renting a room from me... He claims to have "bent a rod" however the heck you do that with a stock long block in a carburated off road buggy.... Anyway I'd like to either see if that 350 is repairable cheaply or just put the heads on my 305... I can't afford to take it to a shop right now... But if you'd be interested in checking it out sometime let me know... I live on 1960 near 45... Maybe I can do something in return for you if you're up for it. Sorry if this is considered "stealing the thread" but I saw you talking about Vortecs & my fingers started typing away... :-)

ouch man.. dont worry about it.. $hit happens.. i blew my first 383 the second time at the track.. not even 2000 miles on the motor either.. threw 2 rods, bent 4 valves, twisted the crank and seized the other pistons to the rods.. it was a mess.. all i can say is, if it aint broke dont change it.. if it is, build it better..

ZONES89RS

Yea, its all good man, i have the hopes the rest of the rotating assy is still good, i will beglad the more i can salvage ya know?

That's a bummer alright. You mentioned using the ZZ4 cam next time around. If it helps any, I have a ZZ4 cam (used) I'd like to sell. -Bill

I feel your pain. I swallowed a valve in my 86 last year and punched a hole in the top of the #1 piston. S*&t happens. Found a 4-bolt 79 truck 350 block. Going to build a 383 for it as soon as I collect all the parts.

Sucks to hear Zane!

I have a brand new set of 350 .030 over Speed-Pro Hyper flat-top pistons and rings for sale if you're interested...

ZONES89RS

iTrader: (2)

Well, how much you asking for them Mike? I might be interested, i still have options open, i dont know which way im going yet.

1bad91Z

iTrader: (1)

$175.00 brand new in the box with brand new matched rings...

BiGgE

iTrader: (2)

Thats a bad one...did you get lucky and not break the block? I know when I blew mine up, I broke a rod, and took out the block, tweaked the crank, bent 2 valves, took out my cam, took out 2 pistons, not to mention the oil pan, pump, and a couple of solid roller lifters. Hope you get yours going again soon...

ZONES89RS

iTrader: (2)

Well, i havent removed the engine completely but this far it is, busted #3 bore, hole in the head and a beant rod, not a large piece of the piston was able to be found.

iTrader: (6)

Did you find the missing valve?

ZONES89RS

iTrader: (2)

Not yet. I might have the rest pulled out today, still looking.

Mr.Wolf

iTrader: (1)

you working this weekend, i'll bring out the camaro and help you tear down check the block and everything.

ZONES89RS

iTrader: (2)

Yea, i gotta work. Its not a big deal, nothing to check till i get it out, the blcok needs a sleeve, i just need to see if the crank and cam are still good.

Mr.Wolf

iTrader: (1)

ok then see ya at the meet then.

ZONES89RS

iTrader: (2)

Well, the head is junk, the block is not reccomended to sleeve for my application of power. What a loss, oh well.

Damn.... that sucks.

Just wish i had the money to throw it together and get it on the road again in a week.

Sorry to hear that Zane. I still have the ported fast burns that were on my car. Also have the Super Victor and RPM port matched as well. Have all hardware including springs for Hyd rolller and solid roller. They would still be on there if I had re-torqued the heads. Head gasket was good, some head bolts lost torque. Call me if your interested. I will likely post these heads for sale when I can get my pics in order. 281-389-6150 Dave

Thanks man, i am looking for a vic JR intake but that is about it, ill call about the heads, i have a friend looking for a set.

Torqjunki

iTrader: (1)

These heads are better than I thought. So far, the car is only a tenth or so faster with nothing but the head swap. Now running the Afr 227.

ZONES89RS

iTrader: (2)

Damn, whoever ported those knew what they were doing, they look great, i need to let my buddy know about them tomorrow and see what he sais, PM me a price. If not ill call you tomorrow.

Torqjunki

iTrader: (1)

I ported them myself. This is not the first set I've done. I started out doing the iron Pontiac heads which are very similar to the SBC's. I have picked up the Pontiacs 80cfm with stock valve size! I have my heads flowed several times during the process at local machine shop with 28" bench.

ZONES89RS

iTrader: (2)

Damn, wish i had access to a flow bench for cheap, would be awesome. I do decent on heads but i have never had the chance to have them flowed.
