holy shnikeys! thats a dam good find Jeff, I will need to take that in to consideration! DIBS DIBS DIBS DIBS!!!

LS1 6.0 heads eh? Sounds like he doesn't know what he's talking about. But he does say that they flow the same as the 243 heads....so are they the 317 heads then?

 

I think those are SBC or BBC heads, not GENIII.

 

well all I can do is look at em and make sure they're right. Its easy to buy stuff from R-tards cuz they dont know what they've got

ah, that would make sense

 

I put 862's on my wifes 6.0L Tahoe (LQ4). I did however have 2.0" Ferrera intake valves put in. I put them on unported, but do plan to port them later. I also had them milled .015. I'll see how well it does tonight as I should finally be able to drive it tonight.

 

Keep me updated Zippy.

 

you can always pic up a set of 317s for about 150 and get them milled down some

 

Well, going to be a bit longer for me. Going to have to get another 6.0L. Block is cracked where the starter pad comes down off the block. At least I was able to hear it fire up. As for the 6.0L heads, they do make very good power if they are ported with good valves on them. A friend of mine has a T/A with an LS1 making over 400RWHP with them. That is with only a TR220 cam, LS6 intake, long tubes, Corsa cat back, and my tuning. He has trapped 114+ in bad weather (bad enough that I was .8 slower myself that day than my last time out). He also doesn't run a sticky tire and can't go wide open until just before he shifts to second. I should have another engine ready to go in by the weekend. I just might port the heads now though. I was really itching to see how they'd perform with the bigger valves unported though. I think it would be a great test to see how they would work for someone in just a bolt in form. Baker Engineering did the bigger valves for me and did a very beautifull job as well as at a great price. If I can put down more than 350RWHP to the tires without headers that would be great. I'm going to have to dyno it in second gear and show less power as a result since I haven't ordered the GM high speed driveshaft yet and the SUV driveshafts tend to break on the dyno when spun up.

 

wow, very good info Zippy, sorry to hear about ur block.. hopefully mine will hold up.

And thats 726.0Chevelle, thats also definitely an option since funds are kinda tight on this little project, still need to find an 80e for when I desimate my 60e
