    Modding.

    Should I even bother?

    Pulling engine and trans to change front seal, what should I tear down/look for while it's apart?

    ^^Hmmm, not necessary.

    I'd pull the front cover on the engine and change the timing chain and put a new chain dampener on it. Get a new gasket and possibly a new WP and gasket too if you wanna toss the extra 30 bucks at that. Get a new rear cover gasket too...trust me...with those many miles they deteriorate and that'll be the failure of the engine when it denigrates and you have no oil pressure and spin a few bearings. I'd take off the top end too and do new coolant elbows and LIM gaskets; aluminum ones. Get new plugs for it along with wires, new PCV, fuel filter, etc...just a big tune up. Check the engine/trans mounts too...you can get new solid rubber replacements from AutoZone. I'd get rid of the Dexcrap too in favor of green or yellow coolant.

    do yourself a favor and hook an oil pressure gauge up to it. see what kinda pressures you are running before you even touch the motor. if they are low and ****ty then its not worth modding it because youll need a new motor after you put more heat into it.

    I was planning on hooking a oil pressure guage up to it before I pulled the motor out anyway to see where I'm at. What's normal for these engines?

    Would it be worth while to L26 swap it if I can get one for cheap?

    if youre idling at anything less than 20 psi when the motor is hot then its already done. even then you should see more than that.

    wow 8 psi with 5w30 my 19 year old SBC 350 with 226K on it ran around 15psi hot with 5w30 in it idling at 500rpm and and 25psi at 2000rpm, the poor thing was beat in a work truck. It would bounce up to around 45psi at 3k or so. But it had an occasional main bearing knock on startup.

    Haha. Your truck wanted to be a Ford.

    But, about the L26 swap? Is it worth it for $300? What is involved? Wiring swap etc? Or is it direct swap?
