June 19, 2011I have a 98 F150 with the 4.6 in, and it has just over 363 000 kms.
HereÃ¢â‚¬â„¢s my plan- buy a used 4.6 (98-03, hopefully 99 and up) and slowly build it up in my garage for when my current engine canÃ¢â‚¬â„¢t meet my demands anymore (towing, etc). I donÃ¢â‚¬â„¢t have a huge budget either, but doing the build over 1-2 years I can slowly increase my budget.
My criteria is for the new engine to be installed without any problems- computer, engine mounts, etc. the new engine will be used to tow around 7500lbs (max prob) and be a daily driver. MPG is a must but willing to suffer a bit for more power- but my top priority is reliability. As in going out to the truck at 6:00 AM in a blizzard quite a bit below zero (I live in Canada so it also has to pass the E-Test ) and it firing right up as it does now.
Then I want to slowly build my current engine when its out and put it in another f150- this will be my performance truck so I can put performance parts on there (hello supercharger lol)
Here is what I was thinking- tell me if I am wrong or can do something better with my money-
Forged crankshaft, pistons (what type? Dish, etc), camshaft (higher lift)
Then the usual bearings, plugs and ignition wires (what type-good for mpg and performance), etc
Bore cylinders- nothing wild.
Btw, I already have a flowmaster muffler.
I basically want a mild build- as in just better then stock.
The new engine is going to run me somewhere between -2-3 grand- so I would like to only put in another 2-3 grand (absolute max and really pushing it is 6 grand total- I can do labor except for the actual install)
What sites should I order parts from? I prefer local when available. Should I just do a stock rebuild? What should I look for with a second engine (years, etc so I donÃ¢â‚¬â„¢t need to change anything else like computer- I want new engine to basically bolt up)
The truck is in amazing shape so I donÃ¢â‚¬â„¢t want to sell it.
Let me know what everyone thinks- thanks in advance
