Hello ppl. Im not sure if this is a right thread or even if this is the right forum but when I google "5.4 dohc" stuff, most of the time Im ending up on this forum ,so Ive decided to register in here. Also wanna apologise for my English because its my second language and my English grammar is lame , so dont throw rocks at me
So let me introduce myself. My name is Anton , Im from Estonia EU. Was born in USSR and my native language is Russian. That's it so far
Now to my Q's. I have 99 Lincoln Navigator which I bought a 1.5 year ago. After some of the exhaust valves get burned Ive decided to restore my car completely. So now its completely apart in a boxes in my garage. Body of the chassis, gearbox and transfer case on the table getting rebuild. I took engine apart as well , took some measurements which told me that I have to do cylinder boring which means total engine rebuild to me. Heads are in good shape.
In the beginning I was thinking to put stock parts but now I want something better. I dont know many brands who provides performance parts for those engines so Im watching on mmr stuff. Also I have to mension that the engine is gonna be working on LPG as it was before. Bad LPG system adjustments actually the reason of burned valves .
This is a pretty rear car in my area so there is no ppl to ask in here what is better for me to do with my engine. I dont have a lot of money to buy some fancy heads right now or even better camshafts but Im looking in future on those. Right now i have many boxes with new suspension parts, new timing set, oil pump, gaskets etc. Body and chassis going to be sandblast as fast as weather will be better. Only question is the engine. Im going to do heads porting very soon. Going to leave stock cams for now. As i already understood , cranks are very good on those engines.
What you guys will suggest ? Does it even worth to buy performance parts for me? Any thought on 4r100 tranny?
Im thinking to buy performance pistons , rings , roads , pins, main bearings and piston roads. Thinking to leave stock heads and cams with all new valves, stock but new rockers and valve adjusters for now. Is it ok to do like that for a year or two so later I can install other performance parts to get more power?
Also what could you guys suggest to do with the engine for LPG? Bigger compression ratio?
Actually I have no hope to get answers but it worth to try to ask at least
Here is very few photos of my project . Thanks for your time.
