low tech drive line up grade (IMO)

well Im getting closer to completeing the engine build for my Mark VIII <-- (not a typo) it is a normally asperated 302 stroked to 347 with a .040 over bore I guess that makes it a 349 cu in I dont want to bore you with a parts list but I will say that the calculated horse power should be around 420+ with out having to run some type of compressor power adder it will be backed by a modifyed c4 trans now you may ask your self why on earth would someone remove a 4.6 DOHC engine and try and mount an engine that dosent belong? and you may ask if you really must do this why not a mark VII ? well the answer to the first question is I have enjoyed my mark VIII but I dont want to upset anyone but the trans just keeps on breaking and it cost a lot to fix and with out going into a lot of detail a lot of things seem to break and cost a bundle to fix so I got to thinking that I would replace the engine with a push rod engine the 302/349 sounds great has gobs of low end torque 349 inches of displacmet and is dimensionaly smaller than the DOHC and with aluminum heads and intake the 302/349 weighs about 425 lbs and has lots of room for headers the c4 trans is light weight and can hande the power.
I could quote specs all night but lets face it we all have these cars because we lke the way they look and ride and as great as mustangs and camaros are there are way to many of them . its all about how it makes you feel and I think that a pushrod motor will give the mark more of a hot rod feel second question why not a mark VII ? well umm lets just say that they arnt as nice looking as the Mark VIII :)
well I opened the hood and was going to start removing the 4.6 and I know that the prefered method is out the bottom but I just dont have the equipment required to drop it out the bottom and to tell you the truth even though I have read about doing this till my eyes bled I still cant picture doing it safely by my self so do any of you have any tips for removing the engine from the top?
thanks for listening to my rantings Please dont hate me for using a different driveline the mark VIII is great but I think mechanical things should be as simple as possible but still be able to do the job

Sounds cool. Why not an AOD though? won't a 3 speed kind of limit you in normal driving?

I'm sure it can be done from the top. You'll have to remove the hood, radiator, and a bunch of other crap. It won't be fun but just unhook everything, get the radiator out of the way, and lift 'er on out.

It wouldn't be difficult to remove it from the bottom, even by yourself. I have an $80 motorcycle jack that i used to remove/install my k-member. That and a pair of tall jack stands, out she comes. Only problem is then you can't roll the car around because there's no front suspension on it.

I like the sounds of the engine swap. I think you'll find members here that might be interested in hearing about your progress. Feel free to post as many details as you can and take pics for us.

This could make a great tech write up to put on here when your done.
man I wish I kept my Mark VIII. I sure do miss it now. Love the Rover, but it isn't a Mark.

"why not an AOD ?"
what a great question!!
well today I ask myself the same question (man it would be great to have a extra gear for freeway cruzing) then I started to do some research
PROS
better mileage
higher top end
decreased engine rpm longer engine life
plus its just nice to say you have a 4 speed
CONS
its heaver
its larger
it requires more hp to drive it
and I dont really understand what size converter/flex plate/starter/adapters if any I will need
and it is related to the trans. from my mark that I had so much trouble with
.......................
I havent ruled out the AOD yet but I need to understand it better first
 
RE: low tech drive line up grade (IMO)

well I went and did it now I just bought a c4 that was built to handle twice the power that my stroker will be putting out . . . the AOD was atractive for a while but I find my self much more attracted to the compact low drag bullet proof c4 . this will be a purpose built car that if done correctly will show that a lincoln mark VIII with all the ginger bread and tinsel removed can clock low quarter mile times without having to resort to artifical power adders like forced induction or nitrous oxide all while being streetable and having a long life 100,000 miles or more by sticking to the basics
but more than anything I just want to have a cool car that dosent look like everything else out there

did I tell you guys that I want to to paint it screaming yellow? :)
