Review Of Is The 4.9 Cadillac Engine Good Ideas. A slicker automatic now complemented the engine with prompt, smooth gear changes. The 4.9 l was replaced by the new 4.6 l cadillac northstar engine.
The mostsignificant aspect is always providing good care to your suv and keeping up with the regularly scheduled maintenance intervals. A new camshaft and crankshaft balance minimized engine vibration. A new oil pan accompanied the oil pump.
No Economy Improvement Occurred, So Expect 25 Mpg On The Highway But No More Than 15 Mpg Or So Around Town.
Now i will really love my baby! While the eldorado would retain its exclusive access to the 500 cubic inch cadillac v8 until 1975, in its second year gm would drop the engine's compression ratio from 10.25:1 to 8.5:1. That would leave only the n* and the 4.x engines.
The Original L37 Features And Performance Produced.
The l37 northstar was the original northstar engine, producing ample responsiveness and power, which shows the consumers and the companies how the norhtar engine can be quite good. Good luck on your next purchase. A new camshaft and crankshaft balance minimized engine vibration.
I Put 241,000 Mikes On The Engine Without A Transmission Or Engine Job.
By this time, it seems to have become a good and reliable engine, if not that powerful. okay, i guess he dismissed the 4.6l altogether, but not that powerful? Also added were improved pistons to minimize engine noise during cold starts. The life expectancy of the cadillac escalade is up to 200,000 to 300,000, but there are a lot of factors in play.
Not A Lot To Choose From.
The 4.9 also featured a new oil pump, which increased oil flow by 13 percent and oil pressure by 18 percent. The oldsmobile toronado and buick riviera, cousins to the eldorado, had olds 307's in them from 1981 to 1985, and that is a pretty good engine. The ns has higher peak torque and hp numbers, but they happen higher up in the revs.
The 4.9 L Engine Was Used In The Following Cadillacs:
The cadillac northstar with a 4.9 liter v8 engine was introduced in 1991. Hello everyone, im new to this forum, so exuse me if im a bit of a dunce here.i have a 91 cadillac sevile with the 4.9 engine.i have plenty of external upgrades such as an msd digital ignition, custom cool air intake, flowmaster exhaust (dual camaro style outlets) and advanced timing (6 degrees).
