i wasnt aware of this until mine broke, than i read it happens every now and then... I think gm has a tsb that says use a different set of rings, and it gives a gm part number...

#7 melted piston,stock injectors fast 90,afr 205,tr 224 ,lost compression,blowing oil past the rings wasnt too good but block was fine,thank the lord above.which now gave me my 383 with forged bottom.

^ I am pretty sure this guys blew up because of detonation... Not enough fuel in #7, stock injectors + afr heads + cam + fast = not enough fuel.

Omg. Wow. 35k. And I thought 80k was bad. Was it covered by warranty?

I lost compression on #7 a short while ago. Been busy lately but am going to try to get the engine out and pull it apart to see what happened this week.

a lot of people say that well its not worth Changing out the "Injectors" all i have to say is 1 thing. If your'e to Cheap to buy a set of New Injectors get a Set of Gto "Injectors" there on here and on cars at ur local scrap yard . This ususally is like what there saying light/or heavy mods or stock redlining and then the Engine goes lean trying to keep up addiquite fuel flowing thought the combustion chambers.Then Dam #7 IMo with tuning with Hp tuners and all the ls1's in Vegas.

my number 7 let go too. i never exactly figured out what happened.


when i put my new motor together i had my SVO injectors cleaned and flowbenched, and i made sure to put the 2 highest flowing ones in 7 and 8

Knock on wood, I haven't had any issues, but just like everyone is saying, I put my highest flowing injectors in the back and worked my way forward going from 7 to 8, then 5 to 6, ect. Also, I keep my tune via wide band at 12.5:1 on the street, which on the dyno would probably read more like 12.2:1 because of less load. It may seem to rich, but time and time, people have shown that running 13:1 might not cause knock, but it will be a matter of time before you hurt #7.
