Engine Question
 

My 72 Malivert is using oil and fouling plugs , the engine is a 290 HP crate motor with lots of hard miles on it . I have the original 350 with 55000 miles on it . It did not smoke or foul plugs but did use oil ,my guess from sitting a long time before I bought it . It was a typical 2 bbl engine . My thoughts are to open it up and see what it needs ,maybe put in a Roller Cam w/ roller rockers and aluminum heads and call it a day .

What says you guys with more knowledge than I on motors ? Just doing some planning ,wont happen right away as Im building trucks right now .

I'm no expert on building engines so I'll sit back and see what others say.

You wont know what they need til you pull them apart.
Cylinder walls scored....crank needs grinding etc.

Buddies 2 bbl motor in a 71 chevelle. Light porting a RV type cam. Headers and a 4 bbl added. Ran 12.7 consistently for 8 years on skinny factory sized tires. Or you could light them up till you let off whichever mood you were in.

I trying to say I would look into just freshing it up some. It be fine.

I would do a compression test and a leak down test. It could be something as simple as valve guide seals causing the smoke and oil consumption.

We did that and changed the valve seals with no success .

Well, it was worth a shot anyway.
