How much horse power does a ls1 roadmaster?

I drive a '95 Roadmaster with the 350 Chevy LS-1. Don't know the HP numbers but it will burn up a set of rear tires in 30 days. From 0-60 in 6.7 sec, it will embarrass any Crown Vic. Factory governed to 110mph because suspension is tuned for luxury. With the optional trailer towing package, it will tow 7,000 pounds at 70mph all day without breaking a sweat. Only '94-'96 Roadmasters have the LS-1, avoid the rest. Awesome ride! Ted In Bama The engine is an LT1, not an LS1. The LT1 is what is referred to as the Gen II, small block chevy, while the LS1 is an all-new version of the corporate small-block, usually referred to as the Gen III. Now, they are up to a Gen V version of this all-new engine, while the Gen II (LT1) basks in no-man's land. It was a good upgrade, but had some serious flaws, not the least of which is the notorious Optispark distributor. I have been fortunate enough to have an Excellent example of the optispark in my '95 Roadmaster Wagon, but I know of some other folks not quite so fortunate. The LT1 in the Roadmaster is factory rated at 265bhp, compared to 280bhp for the same engine in the Corvette. GM's official line is that the difference is due to a more restrictive exhaust manifold in the Buick. The LT1 is also one of the more difficult engines to work on that has come out of GM in the recent past, requiring lots of time for such simple maintenance procedures as changing the spark plugs and plug wires. david in TN
