Recent Events:

Background Info:
- 1986 Chevrolet Monte Carlo SS
- 5.0 liter ohv V-8 (305cid): 180bhp @ 4800rpm and 225lb-ft torque @ 3200rpm stock
- 3387 pounds curb weight
- TH200-4R four speed automatic transmission (3.73:1 gears), RWD
- P215/65HR-15 tires
The current estimated output is 275bhp (SAE net) @ 4400rpm, and 320lb-ft of torque @ 3800rpm. The DesktopDyno quotes about 350bhp (SAE gross) @ 4500rpm, the typical conversion factor from gross to net is about 75-80%, giving us 263-280bhp SAE net!
Modifications:
- Stock 305 thrown out, and a 400cid small-block V-8 installed. The motor was rebuilt and overbored to about 406cid. If you're interested, there is a projected dyno sheet for the engine from DesktopDyno in PDF form.
- Lots of engine accessory bits swapped out: Holley 4160 750 cfm 4-bbl carburetor, Sportsman II intake and heads, CompCams XE268H camshaft, Hooker Headers to dual exhaust DynoMax Super Turbos, CS 140 amp alternator, March Performance Billet Pulleys.
- After you've done the engine, why not throw out the tranny too? It was replaced with a Turbo Hydramatic 350 three speed auto to handle the extra power and torque.
- And while you're at it, those dinky tires gotta go. Replaced with P255/50VR-16 tires on 10" wide rims (in the rear.)
- A monster Howe 2" aluminum radiator replaces the original, with electric fans instead of crank-driven.
- Hurst ratchet shifter was installed complete with, ummm, custom console modifications.
- Intellitronix digital dashboard. Ask Chad about the fuel gauge.
- Spring expanders front and rear to stiffen up the suspension.
Planned modifications for the near future are:
- Install a manual to replace the TH350.
- A limited-slip diff would be nice...
