engine parts

anyone know what 4.3 blazer internals are the same as a syty? i know the crank is but what else?

my sy engine is at the shop and i found out that the block is a 98 block i want to tell him to check part numbers on rod and pistons if they are syty specific.

Re: engine parts

Not sure about the rods but the pistons are definetly not the same, syty have low cr piston. Also the main caps are diffferent.

Re: engine parts

need the info by tomorrow
so we have pistons which i figured
how about rods?
i am 99% sure the cams are te same as well.


any one have any stock parts laying around they can read the part number off of?

i have not used stock stuff for a while

Re: engine parts

To the best of my knowledge:
caps are nodular and SyTy specific
rods are non standard, are supposed to marked with a paint dot but I forget the color.
Pistons are not the same.
Cranks the same, cam I believe is standard to the LB4 series motors.

I'll have to add this stuff to the parts compatibility thread once it's hashed out

Re: engine parts

just the pistons, heads (different years) & SY/TY are 1 peice seal cranks. SY/TY are Z blocks.

Re: engine parts

The Main Caps and Piston are different. The rods are basically the same. The cam is slightly different than LB4, but difference is very slight

98 block will have have more agressive cam (good thing). Do you have a cast aluminum oil pan? You could easily rebuild the 98 block with low compression pistons.

Re: engine parts

then i would die i am buying something new but it is a secret for now. i will not be buying it for a littl e bit though maybe 6 months. new with a warranty and i dont have to worry about bad things since it will be covered, or at least that is the idea. i have not bought a new car since 01 and that was a ws6 and a big pile i am hoping for a better go round this time.

He will definitely mod it what ever it may be. He'll probably say he wont now but he will. He can't help but to mess with it somehow, it will drive him nuts if he doesn't do something to what ever it is.

Re: engine parts

I have gotten better and better about not modifying my daily drivers (and wifes as well) Our current daily driver just have K&N air filters if you call that a mod, that is a huge progress for me. Personally its nice to have something that A has a warranty and B I don't have to work on.

Re: engine parts

How strong are the rods? At what point should I consider when doing a motor build for high hp replaceing them? I have heard they were crap but I am not sure at what point they crap out.

Re: engine parts

thats the plan.

but as jeff says i have never been able not to mod something, even the tahoe got modded but it took a year to do it.

Re: engine parts

What is bad is that my wife has gotten the bug....it is good but her wanting to mod her Yukon we just bought her is cutting into my mod money. I am afarid to make her wait because I have always wanted to mod her cars. So far to her Yukon XL we have lowered it, done all the free mods to the motor, tinted the windows, and am waiting for my paint and body guy to work us in. Not bad for having it less than 2 months.
