i might as well do things the right way... if i had the money. im 19... working construction and i make $9/hr... with insurance and high gas prices for my little gazz guzzler. so it's gonna take me a while to get this car where it needs to go. and right now it needs to go back on the road--without backfiring under acceleration. so im wondering...while i need a vehicle if it would be smart to replace the cam, pushrods, rocker arms and springs and i'll just reuse the newly installed lifters. the compression on the engine seems to be near perfect, and the engine never blows smoke under any condition. assuming the engine isnt planning to fall apart anytime soon, how long is it usually known for a older engine with a new cam replacement to last? i figure it's not worth my time pulling the engine if i dont have the time to rebuild it completely so i'll be leaving the engine in and replacing the cam by removing the front clip of the car and using the same old cam bearings. im hoping this will help me get by long enough until i have money saved for a new engine.
