It's a iron block an the head ports are the rectangle one. The place said it was out of a 09 it could of been a different year for all I know lol

 

the 07-10 6.0 is the exact same as far as i know. i wouldnt put too much thought into it other than does that **** have VVT and DOD??!? if so then get ready to sink a couple hundred in pulling that dod and vvt out.
just so you know there is a p/n list for the dod delete

 

Yea I've already removed the DoD and vvt so that problem has been solved. I'll be givin Pat G to spec me a cam out next step possibly injectors and intake porting

 

OTE=iamkeniff;5037980]Id have to see a log from a dig on DRs, and id have to see the tune to tell you. Thats plenty of cam to get that thing to 7.99 1/8th mile. Either its not enough timing out the hole or too much. KR out the hole or its got KR throughout the run. IATs are too high, something. If i can 8.0 1/8th mile in a 560bs truck then i know a rcsb can 1/8th mile better[/QUOTE]

Silverado1ss89 is at 12.8afr 28° timing shifting at 6500... I'll c if I can find his logs and send them to U..
I believe he has traction issues at the track he's only going 2.0 60' ...

 

those heads can handle and move heat rather easy, throw some timing at her and let'r eat, just read the plugs, NA 12.8 is weak, go 13.5 i did it for years on my lq9 short block with alot more timing

 

6700 shifts
Also whats the timing at the dig?

 

I added the stock iridium Ac delco 41-110 .. Should put another spark plugs ??

 

every combo is different. some engines may like it. others may not.

 

very true, that's why reading the plugs to find out is so important you know nothing about the engine and what it likes or dislikes if the plugs aren't read, i listened to so many people on here until i was blue in the face until i learned how to read plugs, cant believe so much was left on the table. just saying!!

 

I run TR-6 in my 6.2 (26* of timing) and TR55s in my 5.3 (24* of timing)
