"Recession Buster" build?

Hey guys, I have the chance to pick up a complete Lincoln MKVIII for dirt cheap. I thought about swapping in the entire engine, but it sounds like more work than I want to deal with, and would be making less power than my full bolt on 2V. Then someone suggested I do a Recession Buster build, using the 4v aluminum block and internals with my 2v heads, cams, and intake. It'd bump my CR to around 11:1 and it sounds like I'd be around 330rwhp. I'd also be losing 85lbs ditching the iron block.

The swap seems pretty easy, with 1 hole needing drilled for a coolant passage in the new block. Has anyone ever done this, or know anyone that has? My main concern is if I need to notch pistons or degree them in afterwards.

What cams are you running in your 2V?

Honestly not sure. The PO wasn't the one to put them in and he couldn't remember what the owner before him said. He believed they are Comp Cams 268 or 270s, and hearing sound clips from other cars, they sound similar. It's got a fairly choppy idle. I wasn't able to see any markings on them when I had my covers off either, unfortunately.

Well, I have the 268s and i have PTV issues on my stock PI engine. I would venture to say yes you will want some notches AND you will want to degree them in.

Do cams usually have any identifying marks on them? Or is there really any way to tell what they are?

I can't think off hand when I put my 268s in. I would think Comps would have something on them but I'm not totally sure.

There should be a part number etched into the cam. The recession buster is a great way to build and get nice results. I would double check your cams and make sure you wont need something a little bigger for the compression bump. Fly cuts are easy to do with an old head and some sticky sandpaper.

If the Mark8 engine is healthy, throw some decent cams in it, lt's, IMRC delete, dyno tune and call it a day. Sell your 2V complete to recoup some of the cost. Your stock PCM can run that engine just fine, but you need to either delete the IMRC's or tie them open as your 2V PCM cannot operate them.

And in doing the above swap it will keep your c/r at whatever a stock Mark8 is (somewhere between 8 and 9:1, I'm not sure what the actual number is) so should you later on decide to add a "recession buster" centri then you're good to go.

If interested, let me know and I'll link you a really well detailed Mark8 swap thread from somewhere else.

Perhaps. But more in a "bear" sort of way, rather than "twink" gay like vtec.

If you sway that easy, you dont deserve that 2v!

Some of them can be "bear" gay while others are still "twink" gay. I only say this because the 2v's have better features that allow more compression without detonation than the 4v's. The 2v heads have a "swirl" port while the 4v heads have a "tumble" port. Swirling a mixture keeps it homogeneous better than tumbling a mixture, therefore when increasing compression a 2v head is less likely to detonate than a 4v head.


I like compression...

I would run the 4V, but I'm not wanting to drop $1400 on cams, $500+ on an intake, and $1000 on headers/exhaust right now. And it'd make maybe 350rwhp.

Keeping the 2v heads, cams, and intake, the money I save could be used towards porting the heads and notching the pistons, along with all the odds and ends like gaskets. And still make around 330rwhp. Heck, I could get even bigger cams and better valve springs too.
