Sweet - you got the polished intake.  That'll look nice.

[Wild Bill]

I got chrome alt, valve covers, oil pan, timing chain cover too

[Wild Bill]

Total cost for the long block with engine upgrade was 2400, the intake was 360, the chrome parts was about 180, harmonic balancer was i believe 200 something, bought new pulleys which was almost 400, billet distributor was about 300 also, so all in all, so far i've got around 3700 in this engine... plus a 7 year 70,000 mile warranty

Great build!

[Rick]

That looks pretty sweet!  I do have one question, though -- and I've been noticing this a lot recently -- why weren't the pressed-in/freeze plugs painted engine color?

[Wild Bill]

No Idea

[RPO_Z06]

I really hate to point it out since its together already but I think you have a 6x4 (4 is 91 cc's) on one side and a 6x8 (8 is 98/101 cc's) on the other. Unless I'm seeing the right side picture wrong.

[Wild Bill]

let me go check

[Wild Bill]

If you are looking at where it says GM 4  GM 8   I'm not sure what that is for but the stamp code is on the other side of the head, and both heads are stamped 8

[RPO_Z06]

Cool.. I thought they might be different since your dates were two years different and it would be better to know now.
The GM4 and GM8 tells you if its a 6x8 or 6x4 head, that's how you tell what cc version of 6x head you have, or at least that's my understanding anyway.

[Wild Bill]

Um, I'm not sure about that..

[Wild Bill]

And where it shows "stamped ID #" on my heads it shows 8 on both heads

[RPO_Z06]

I'm not either, maybe someone in the know will chime in.    I like your cam choice.

[Wild Bill]

Yeah, I'm hoping it will turn out great...
It should have a fair idle quality with lobe, it's recommended for mild bracket racing
