Need technical info on 3.2

[zak]

Also, any cam information would be appreciated. Especially if someone knew the factory LSA (if this is possible on a DOHC engine).

Camshaft data:
http://www.shonutperformance.com/SHONUTCams.htm

I am not sure SHOnut quotes LSA numbers there. There is another list member here who has looked at LSA on the +40 cams specifically, I suppose he may pipe up at some point. The factory MTX overlap is tiny, I recall that much (5 degrees or less).

Will you be doing any engine modeling using software? If so, would appreciate it if you could run some numbers for me (my application is max reasonable rpm ; - ).

SHO amo, know ye not of Teflon coated differentials?

The only software I really use is a DCR calculator. I make this calculation the foundation for building an engine. You can download it here: http://cochise.uia.net/pkelley2/dcrvb6.zip.

nope im not much of a trans guy. when it comes to the trans id just drop it off at the shop and say i built a motor that makes 500hp, make the trans worthy.

REMOVE IT!!

Bad things can, and do happened!

'nuff said.

Uggh, I was in the middle of "save a copy" process on my work PC when I read this... I hit the Stop button in Explorer about halfway through...

Do you think this will be problem? Do these guys not take kindly to people saving this document? Why have it available online if this is the case?

 

[Sho Amo]

it just wasnt supposed to be posted supposidly. only pm'd because it is illegally shared.

You asked about a manual that has all the specs. Go to ebay and get you a set of ford shop manuals, a two book set with a wiring book and another book on vacuem. Expensive but worth it. If I remember right the piston deck clearance is .002 out. The gasket is around .085 than you have a crush factor on there. combustion chamber is 47.0-48.0 cc volume.

Do the project, keep it N/A, but plan on opening up the intake manifold, the intake and exhaust ports, and polish it all. Also remember when you lighten everything to get a better than good balance on all of the rotating assembly.

Actually, I uploaded the document. I bought the book (for like $120, mind you), scanned and OCR'd every page, and put it in PDF format.

I have not received any communications from, er, certain car company regarding this, but apparently SHOForum admins did, for hosting the link to it. A shame, really. It's not like they're producing this book any more.

Anyway, all I can say is, http://www.alfitz.com is an excellent website, and you should check it, and all its links, out.

Maybe I'm not reading the manual correctly (I too was thinking that the number should be .030-.050). Here is a screen shot of the specs.

Maybe "flatness" refers to tolerable variation rather than "thickness".

correct.

before I replaced the engine in my turbo ATX car I was going to swap it into a windstar sport. 400whp of furry I thought would be a blast I thought. I am really just not sure if A N/A SHO engine would be worth the trouble BUT if you are going to go with aftermarket pistons anyway might I recommend getting HD pistons that are NO2 ready just in case you are unhappy with the N/A results.

just rember it is cheaper to turbo or supercharge and you get more power with the same reliability at reasonable power levels. Just because you turbo or supercharge doesn't mean you have to go bonkers like me or some of the other guys. 8-10 psi is tons of fun and you arn't going to burn up ATX transmisssions at that boost level.

On the actual swap:
my research found this to be a pretty straight forward swap. The subframe appears to be the same as the ATX SHO. so use windstar suspension, rack, and axles and I think it will bolt right up, BUT also note what else that means... did you guess it yet? continental swap. They dont rev high like the V6 SHO and won't make the power boosted (comparing stock for stock engine strength) that the SHO will but it has 2 important things the SHO doesn't.

Thanks... maybe I'll give SC another look.

You lost me on the above... I didn't "guess it". Can you clarify what you are talking about?

Also, are the "HD" Wiseco pistons? I'm planning on getting forged pistons. Would you bore it out? How much bore would you do? Thanks!

Continental? Isn't that RWD? Did Ford make a V-8 that bolted up to the AX4S transaxle? Is it a 4.6 modular or 5.0?

i always remembered that it said intech on it. i dunno what that means tho.

That is GREAT help. I haven't seen anything out there to say yet what the piston to deck clearance is, but I just read that the head gasket thickness is .002". I think ideal quench is in the .003-.004 range. I also read that the SHO heads are hemis. Are they symetrical? Does anyone have a photo of a SHO compustion chamber? Are the 3.0 and 3.2 heads identical?

Stock 3.0

Looks to me like the pistons don't quite reach deck at TDC... unless it is measured to the highest point of the piston (piston/deck clearance is measured to the edge, isn't it?).

Thanks for those pictures!!!

Very interesting... seems that it was bolted up to the AX4N transaxle (same as last generation SHOs). Also, AX4N was in the 2001-2003 Windstar... maybe this would be a good project for my other van.

 

[SuperHO]

that'd be a wiring nightmare...just ask the guy who tried to swap one of those into a cam failed SHO on TCCA....

SLV, I have a '99 'star. If something like an Intech swap would get significantly more mpg out of it I might be interested in helping figure out which wire goes where.

BTW, you now have all the data you need to calculate the piston height vs block height, between what I've posted and that found in the engine manual.

By the way, the 3.2 pistons are flattops (they still have the valve reliefs) vs. the slightly domed 3.0 pistons.

many thanks! That should make things a little easier.
