|tailhole||Two things I dont like about the pistons is they don't have pressure oiled pins and they use the 5/64 rings instead of the 1.5|

|tailhole||What sucks about this 4.6 I'm trying to build now. Is I keep selling my blocks I have. But I rather have the cash. Still got to make a living.|

It's there ICON brand.
It's a forged piston not that other crap with the KB name.
I have used this brand a few times they seem fine. I will put then at the same level as like probe. But for a shelf piston and for no more than what I need them for there more then nice enough.
I'm work out doing another that looks like I'm going to offset grind the crank .090 and use a 2in small G Chevy rod at 6in long and bore it 4in.
The only thing is, looks like im going to have to put 6 flange sleeves in it.

|Gunner||Are those KB's. That looks like a nice piston. Gas expansion cut on the ring land and the pin is not in the oil ring. Full quench band too. Been waiting for you to post more goodies.|

Finally got off my butt and ordered my pistons

|Gunner||Nice. I saw some flow numbers for a 2.5 stroker head with 2.02 and 1.6. Intake number was 300 cfm. Didn't give any lift or other numbers. I have heard that the 2.5 is based on the 4.0 head. Man I miss this stuff.|

|Gunner||I miss the high tech stuff more than anything else. In that respect retirement sucks. I loved to go into the shop and do little things to my motors late at night. My wife would come in at 3am and find me porting a manifold. LOL those days were fun.|

|tailhole||Funny you said that. I got a mower last summer that can mow at 12 mph. Haha|
|03-11-2013 01:21 AM|
|Gunner||LOL knowing your builds you could mow an acre in 10 minutes when you were done.|

|Gunner||You can have a lot of fun for not a lot of money. Start easy. Rebuild a lawn mower engine. Learn the basics. If you have the basics you can learn the rest as you go.|

|tailhole||I did check retainer to seal, and can't remember. It was stupid, like 750-8 or something|
|03-10-2013 09:00 AM|
I don't use Teflon anymore. They were the latest and greatest years ago.
Valves need oil.
Just like oil restricters, I don't like them or use them. I never understood why you would want to cut oil off to the heads.
What's funny, and I got in a heated confertaion with a big engine builder, is
Why cut the oil down to the heads then run a oil line to the head to spray oil on the springs. He said cus the spring would get hot and the EXTRA oil helped cool it.
I said. No shit? Then I couldn't stand it anymore. What a dumb ass. Haha

|jonathan75||Do you have to test new spring pressure or should it be in spec out of the box? What is the most crucial specialty tools needed for a engine rebuild?|

|Gunner||HAHA I was just gonna say that is one serious spring compressor. I had a smaller one. Had the tips all welded for strength. It was as ugly as a cows backside but it worked sweet. How much retainer to seal do you have when you do a high lift cam? I like the seals you chose. Vitons? They let in just enough oil without starving it long term like the white Teflons do. And it looks like they fit the stock guide OD.|

Don't make fun of my spring compressor,
It's all I have right now. My small one tore up.
This one will do 1000lb and it did these springs just fine. Haha
|03-09-2013 12:14 PM|
And the springs are own and the head is done.
|03-09-2013 12:09 PM|
I'm using Elgin springs
|03-09-2013 12:07 PM|

And spring pressure
