Need some 351w guys in on this one.....
Hello 351w fans.
I have an '84 Bronco XLT.
When I was parked at my place, I wanted to make my Bronco get loud. (straight piped by previous owner)
Really loud.
So, I revved up to 4000rpm with no issue.
I then went to 4500 or 4750, and then an awful knocking set in.
I haven't turned the engine back on in a week.
What can I do? I'm cash strapped, and I don't want to lose my baby.
Thanks FTE,
Marty

Junkyard engine is probably the cheapest bet.
Might get away with a bearing or something cleaning the engine out. But realisticly if the bottom end goes you'd best rebuild the whole thing becouse the rest will soon follow.
Junkyard engine's like theese smallblock v8's don't usually cost much and you'll replace an old carbed lump in a few hours. But of course, you never know how long it'll last and how it's been treated. Full rebuild is always a full rebuild.

drain the oil, look carefully thru the muck and look for metal parts, take the oil filter off, do the same with the oil filter, tear it apart and look for metal parts.
If you find metal parts, refill with straight 30 weight, that's 30W, replace the old oil filter with a new one. Start engine, If it knocks at idle, turn engine off. Find replacement engine, replace engine. Take lots of pictures while you do that and post them here.
If there is no knock, use truck as usual, don't over rev.
Keep an eye on the radiator and the coolant during your first heat up to running temp. You might have a blown head gasket, which will blow with a loud bang, but might reseal enough during restart to allow you to run. If the radiator hose gets hard after reaching running temp, or if there are
bubbles in the radiator, I mean like boiling water type bubbles, then prepare to rebuild the heads, no need for a short block, just a head job.
Keep us posted over in the Bronco forum. Thanks
