If you want a good True Roller, you need the JWIS chain.  They are available from Ed at http://flowtechinduction.com  The JWIS is the best chain out there.

The 5.0 HOs are the only ones that I'm positive came with double rollers. I had an 88 Lincoln motor and it had the standard link chain.

But at 110,000, I'd probably change it.

Yeah, I forgot about the early timing cover.

Got my old 89 crown vic back because the ex thought she blew up the motor that ended up being the timing too far advanced and pinging badly,my old 87 F150 had a double roller timing chain so I presume the 302 in the 89 does too.   Motor has 110,000 miles so just how far can I go before time to replace,the body is about shot but plan on using it for a winter beater until the body or frame falls apart.

The seal in the timing chain cover is also different,it goes in on the inside of the cover on the 70 part and from the early 80s and up the seal goes on the outside and only balancer needing to be removed.

I had to make sure that snorkel was functioning on my 87 F150 so it would idle decent when in cold weather but it still was never quite right.

I am assuming you want a Forged steel crank and not a Cast steel crank?

I would look at aftermarket ones as they cost less than a genuine Boss crank.

I have used Eagle forged 3.400 stroke in my 347 and 8500 rpm without problems.  We also have a 3.850 stroke Eagle in our 412W and after 3 years use reinstalled all bearings.  Both engines are 0 balanced.

Oh, by the way the 347 uses a 2 piece seal and rear crank area is smooth without a slinger made on it and no oil leak.
412 uses a 1 pc seal and no leaks.

You just need to silicone the corners of the rear main cap to block or will leak.  Ask me how I know!

289 And Boss 302 uses 5.155" length rods, normal 302's used 5.090" length rods.

Normal 289/302 rods use 5/16" rod bolts.  People have honed rod bolt holes oversize to 11/32" and used Chevy rod bolts.
289HP and Boss 302 use 3/8" rod bolts.  289HP rod bolt heads were rectangular while the Boss rod has oval/football shape heads.

I have a 1" thick 4 hole spacer (stock Ford one I think??) that uses heater hose returning through it that I have used to keep the carb warm.  I know what you mean about icing up, it sucks.  I have also used an air cleaner with the stove hole underneath the inlet and made somethink to fit around the headers to pull heat from them.

The rear main seal and intake gaskets are the only places of concern. The remainder of the gaskets will interchange.
