I took some pictures of my car last weekend, and snapped some new shots of this car while I was at it.
This isn't my car, but I have more time invested in this than I do in my own cars. It belongs to a good friend of mine, and his son pretty much races it now.
1986 Monte Carlo LS, originally a 3.8/ TH200. Now a .030" over 350, TH400. Stock 7.5" 10 bolt with 4.56s, and the stock posi unit.
The heads are 1968 low compression 327 heads. 1.94/1.60 valves, hyd. flat tappet (OTS comp grind, specs not handy), suingle plane edelbrock, Holley 750 DP. The short block is stock with good hardware and forged pistions.
The TH400 is out of a 90K mile '89 GMC C30. I test drove it, pulled the transmission, put in a Transgo HP kit, and we put a 3800 stall converter in front of it.
It has run a best of 11.57 @ 114. After that run, we discovered a burned piston (hole in it, and the rings were missing...), but it had been running consistent 11.50s-11.70s with that set-up, depending on the weather.
It now has domed pistons, which raised the compression 1 point. We're anxious to see how it will do with higher compression, and 8 cylinders.
Its not pretty, but the work we did is pretty decent. We did all of the work ourselves, and have about $7000 invested in everything.
We have a Dart 230 headed 383 waiting in the wings for this car. But it'll probably need a different rear before that...
