i noticed that when i go up hills i hear a slight knocking sound
i asked my dad to drive it and he said he heard it too and that it may get worse
he said that for the price of a rebuild on the engine i could just as easily drop a v8 in there
now my only objections to this would be, new suspension to support the new engine, new transmission to handle the new engine, new exhaust to replace the 6 banger y pipe and new computer and gauges
should i just ditch it or should i do the engine drop and do all the other stuff?

 

what year is your car? $300 you can get a 4.2 f150 motor which will drop right in with no mods

 

1994 convertible auto

 

I would rebuild your old one and stroke it.

 

stroke it?

and would the 4.2 sound a little more like a v8?

 

are you 100% positive its knocking and not an exhaust leak? these cars are prone to get one on the passenger side weld from the header collector to the front cat. it gives it a kind of ticking noise.

and noa 4.2 will not sound any more like a v8 at all. the v6 is an even firing engine and the v8 is not. it will never sound like the v8.

 

it may be a little deeper since it is .4 liters bigger becuase i kno a 2.8 v6 sounds liek complete rice compared to a 3.8

 

The first thing I would do is find out what the knocking is you heard. Like Amrcnidyot said, it could be an exhaust leak. Then once you find out what the knock is then you can decide if you want to rebuild or do an engine swap.

 

you gotta think of insurance as well. My friend pays 3x what I pay a month for his 00 GT

 

my friend pays 700 less for his GT which is 3 yrs newer and hes only a year olden then me
