Ok, heres the deal. My buddy has a 97 F150 that he just rolled over the otherday, and if his insurance will sell it back to him real cheap, I might buy it from him .

Im mainly wanting the engine and tranny, however Im wondering if the engine could have gotten damaged somehow? When it flipped over he said it was still running and he had to shut it off himself, Im not sure how long it ran upside down though-I doubt very long. Since then he has tried to crank it over a couple times without getting it started, Im thinking he might just need to reset the fuel switch though. There is oil that spilled out all over the underside of the hood too (pretty sure its oil, didnt take a close look at it really).

So is it possible that the engine is pretty messed up (scored cylinder walls, fried rings, etc) or is it probably fine? I would most likely tear the whole engine down and go through it all, Id like to not have to bore it out though if possible .?.? Probably do a somewhat performacne minded half rebuild with new heads and top end stuff, dont really want to mess with the bottom end, I suppose that is that part that could possibly have gotten messed up though.

Any damage that could have been done to the tranny?

 

If it was a short time, the engine is fine im sure. I would pull the plugs and change them...

 

Alright, cool.

A few other questions. His engine is the 4.6 liter, like mine is now. Im wondering if it would be possible to switch just the block for a 5.4 block. If his is a Romeo 4.6 I would need Windsor heads I know (I would most likely get ported ones anyway) and a 5.4 crank (longer stroke). 5.4 intake manifold is wider too I know, so I would need one of those. Is that all I would need to basically "make" it a 5.4 though, or are their way more differences than that?
If it is possible to do that, Im assuming I could still use my coil pack ignition (NOT the COP style like on the 5.4's)

 

Coil pack, cop, same thing, but yes, the bottom end is the only thing that changes a 4.6 to a 5.4, well and the intake manifold, but the heads will work on either, along with all the other parts.

 

I mean the old 4.6 style ignition, with the two 4 tower coils at the front of the engine and plug wires. I dont see why it wouldnt work though.


I didnt think Romeo heads worked on Windsor blocks, and vice-versa.

Connecting rods are the same lenght between the 5.4 and 4.6??

 

Check for bent valves as well

 

Well if your truck has that type, use it, which ever one your ecu is set up for. I would also get a custom tune being as the computer wont know why the engine is using more fuel/air.

 

It will be tuned by TP too, so no worries there.



Jbrew, Ill check that outtoo. Most likely they heads will be replaced and built with new parts though...

 

sounds like you have a nice project coming up!

 

Fun project - Like the new pic built54

 

Thanks! Ive been out of town for 2 weeks without my truck, i get back tomorrow night! Cant wait!

 

I hope so. Ive been looking for a new truck so I can go fast, but I really like the truck I have now. Hopefully I can have the best of both worlds going this route...

 

LOL - I bet!! Looking at your engine Mods/exhaust - The way you did it, from the PI conversion to the tranny ..Alot of work and care -impressive..

I bet it sounds as good as goes, have any sound clips? lol

Good work man

 

Crap, I dont think I can go that long without my truck.

 

If the crank has more stroke then shorter rods are required. If you go with the 5.4 crank and 4.6 rods the pistons could pop out the holes??? not unless the pistons have a different wrist pin location?? Is the 4.6 and 5.4 block deck heights the same?? I'd check with the engine gods about that just to ensure you have the right parts and nothing goes boom.
