Toasted my motor. The rebuild pg 3. It's Alive! 12/18 pg. 4

(In my best Dr. Frankenstien voice) Its alive, Its alive!! woohoo
:drive: The choppyness you hear is an injector 6 circuit problem (found a broken wire in the harness) that I fixed after this video.

Glad to see it

That didn't take too long.

So tell us how was the heater core change? How much of the dash had to come apart?

You replaced all the bottom end bearings. Did you replace the piston rings?

[OH2LS]

Um..... he replaced the motor lol. Got a spare motor and swapped shortblocks.

[SuperSLE]

Yeah Paul. I got a L36 bottom end and swapped heads, cams, timing set, all covers and intake manifolds, and headers. Engine was low milage from Morad. Now I have an extra block to start working on .

I did a write up for the heater core. Hopefully someone will sticky it if they haven't already. I see you have already found it.

[2000Silverbullet]

Doh, that's right. It must have been those pics of the disassembled engine that confused me.

It will be good to have a spare rebuilt block on the shelf..............with some forged pistons.

[00Beast]

You driven the car yet? Glad to see you got it back running.

Yeah, and an XPZ cam, 130# springs, double roller, Stage 4 heads....... Yeah, I'll have a good spare.

Yeah, I drove it to get some lunch today about two miles there and back. Seems to be running very well.

Ah, so that's what progress looks like! Fantastic work so far. I'm not sure if it has been written yet, but am I to believe you're running an L36 shortblock with the 9.5:1 compression rating?

Congrats man. I personally would steer clear of rebuilding a previously toasted L67 bottom end as i only know of a few people who have had any luck rebuilding.

Well I think the block is okay. All that needs to be replaced are all the bearings. And then it should be good. It doesn't need to be machined really, but I will probably have it looked at to make sure.

That is correct. It is written somewhere but gets lost in the mix. I am pretty excited really to see what it will do with the higher compression. I will have a little less boost, but I think it will produce more power.

[2000Silverbullet]

Go real easy on the timing or you will be using your spare block sooner than you want.

[SuperSLE]

Yeah, don't I know that. Going real easy on it for a while. I am a bit scared to break it again.

[SuperSLE]

Well I put about 400+ miles on it yesterday and all ran fairly well. I decided that I had to raise the idle a bit with city driving. It is really annoying when you are sitting at stop lights and it feels like it is misfiring all over the place with the lope. Crappy for city. Fun for track.

I noticed that there is a little more vibration in the engine with the L36 bottom and not so much with the L67 bottom. Could this be the different balance between the L67 balancer and the L36 bottom? How would I balance that back out again if so?

Finding the L36 balancer would be the easiest approach.

I was just thinking... You do all this work to your wifes DD? what is your car then?

I have been told by the GP community that there is no difference between the L36 and L67 harmonic balancers. This is mostly evidenced by L36 guys going for a 5% overdrive balancer and a properly snouted M90. It's still worth a shot if you think you'd want to get that far into it. Maybe there are slight differences.

What's your new idle RPM?

[Jrs3800]

Off the wall question... was the L36 or L67 flywheel used?

[radomirthegreat]

Judging from the belt routing, L67.
