No, they were predominatly LS cars. The guy that put the event on runs a shop that focuses on turbo LS fab so hence why there was so much. I had the only car without a v8.

Well I have a fully machined 3800 series II block with main caps, ARP head and main studs and ARP cross-bolts, bored .20 over. I have a second block that has a full rotating assembly. It will be machined next spring. The main thing I looking to get out of that block is the crank and balancer. I'm building engine before I get a car to put it in or in a few year swap out the 3800 series II block for my 109. I would really like to keep my 109 block in my GN I have right now. However, I hope I can find a roller and do a 3800 series II and be able to run in the 9s reliably without having to worry about damaging the block. I know that it is a craps shot with the 109 block.
Dave Roland worked for GM and he told me that a lot of the Series II/III design came the stage II block. Very stout blocks, I want to see how far one can be pushed. I know the limiting factor might be the 8 bolt heads. Not to mention the stock crank is incredibly strong and there are tons of these blocks around.


Good luck going forward.
 
Cool!

I do want to do a max effort stock bottom end turbo 3800 drag setup to see what actually brakes on these. Im guessing rods and pistons go out around 500hp.

Yeah, after building both a old 3.8 block vs these series II they are way beyond awesome. Factory roller cams, strong mains, cheap starter engines.

Only problem is getting a good trans with the goofy bolt pattern.

What would really be cool is if a forged crank was available to go with forged rods and pistons. Then see if this block could surpass the 109.

Mid 8's have been done on stock crank with FWD with about 900 HP to the wheels. I pretty sure the 3800's are more stout than 109's.

That is what I would love to prove. There are a million of the series II/III block floating around, it would be if they could be put to use and show their potential.

Question is the stock crank forged or a cast piece. I thought I read it was cast from grey iron.

I have two 3800 S2 blocks, but I just spent a ton rebuilding my 109 and transmission. Maybe I can find a decent roller and go from there. My engine builder is also an awesome fabricator. I'm pretty sure he knows how to rebuild a 3800 S2.

Sorry to hijack this thread.
 
Got a few pics of the thing launching. Its hilarious how good is pulls the front up and transfers weight for as stock as it is. Apparently 175k mile blown decarbon struts are good for weight transfer! Haha!

 
I autocrossed the turd last weekend. It did ok-ish. For never competitively driving around a corner and getting lost 2 of the 5 times i managed to run only a second or sl slower than another v6 f body with adjustable shocks and a bit more skill. Its fun, I need more skill though!


And I put about 1000 miles on it this weekend and drove through the rain. My rear floor is that rusty.... If I can find a nicer 98-02 sub 150K mile car in only Green, Blue, or Silver, I will swap the engine but as far as I am concerned, when my front tires are wore this engine is getting pulled and im storing it til I find a nicer body.
 
On the bright side though,

I've put 45K on it and owned it for almost 6 years.
It's run mid 12's
Ive finally turned corners with it
It gets 25mpg at 75mph
It has been wrecked (lightly) 3 times in it's life


This car has paid it's dues.

Looks like the guy in the top pic doesn't like the sound of a v6 lol!

Yup, still following this awesome thread.
