"Temporary" engine
 

While all my friends were out last year beating their cars, mine sat idle because I killed the 302, and decided that I'm building a 410 for it. Well, I just got hooked up with a 347 shortblock. Trading for some stuff I have laying around. Thinking I'm gonna throw my new Canfield's on it, throw it in the car until the 410 is done. It has an X303 cam in it now, prolly taking that out and putting in my .544"/.558" 294/306 cam in, Victor Jr, 750 Holley, pro-shifted TKO II Sounds like at least a low 12 second ride until the new engine is done.

Whatcha think?

They are all "Temporary Engines", arent they? LOL.

I say go for it!

Re: "Temporary" engine
 

sounds like an awesome "temp" engine (a 401 would be crazy!)

Re: "Temporary" engine
 

Why is a 410 crazy? LOL More power is always better! I'm not sure what this 347 will run, but it's gonna be better than the 12.81 I was running with my "stock" 302. That, and I'll have the car out for Steel Valley Nationals, and Fun Ford Norwalk. So, that's a GOOD thing. :D

Re: "Temporary" engine
 

I wouldn't even hesitate to do it. I'd rather be racing than watching from the sidelines. You'll probably have to give the x cam away or sell it on ebay for money towards the 410. LOL.

Re: "Temporary" engine
 

I ran a temporary borrowed engine longer than My engine so far in my car.. ( my stupidity killed my motor )

Re: "Temporary" engine
 

My wife was a "temporary" girlfriend to get me by too. Took her out on the first date, and she never left. That was 15 years ago, prolly the best thing I ever did. Who knows, might end up being really happy with a 347. :D

Re: "Temporary" engine
 

Well, long story short. I decided to go for it. Got the 347 shipped from Iowa, it showed up on Thursday. Took it down to the bare block today (It was FILTHY!) new bearings, new rings, and I'm gonna run my big nasty cam in it too (Brand new X303 Cam and new FMS lifter for sale! LOL). Found some stuff I'm not to crazy about, namely the pistons. No spray for me this year, amongst other things. Learned alot about stroker pistons today, so that's a good thing.

She's back up to "shortblock" status, and the car may actually be out in a few weeks. I'll let you all know!

Re: "Temporary" engine
 

I'll start the bidding at $1.00. :D Glad to hear you'll be rolling in a few weeks.

Re: "Temporary" engine
 

Yeah, what he said. $1.50 :D

Re: "Temporary" engine
 

$2.01! ..and not a penny more

Re: "Temporary" engine
 

I'll give you $2.02 and a reprint Ricky Rudd trading card.

Re: "Temporary" engine
 

Well. now that I think about the piston issue, I think the X303 is going back in because I KNOW this thing is coming apart, and I don't want it to take MR. NASTY cam with it. So it looks like the X303 will be offered up to the track gods, and every run I get will be considered a "bonus".

The more I think about these pistons, the less I like them. Long story, but trust me on this one guys, stay away from the stroker pistons that have the bottom ring around the wrist pin.

Does the current bid stand AFTER it comes out, without removing any bolts?

WTF? Am I on drugs? Putting together a motor that I know is a ticking time bomb? Gotta drive it I guess.

Re: "Temporary" engine
 

Whats the deal with the pistons? Thats normal to have the pin pushed up in to the oil ring on 331/347 stuff. In fact, I dont think you can get it any other way. The 347 uses a 3.4 crank and most likely a 5.400 rod. That leaves you with a 1.100 compression height. They have them listed at 1.090. (.010 in the hole) If you tried a 5.090 rod that would need a 1.41ch piston, but I think the bottoms of the pistons would hit counterweights. My new T-Trim motor is going to have a 1"ch.

Re: "Temporary" engine
 

I just REALLY don't like that bottom ring having NO support above the wrist pin. Evidently (when it was in Iowa) the ring rotated around so the bottom of the 3 piece ring had it's gap out there unprotected. With me? Well, it bent down and scratched the heck outta the cylinder wall, pretty bad. I'm just worried that's gonna happen again.

Yes, 5.400 rods in this one. My 410 cid pistons have the rings pushed way up, and away from the wrist pin. This is the first 347 I've had intimate knowledge of, so maybe I'm just worrying about nothing. ?? We shall see.

Re: "Temporary" engine
 

UPDATE: Talked to tech support at Ford Racing (they built the stroker kit) the guy attributed the piston ring gap issue to the last guy that put it together not paying attention. DO NOT put the oil control ring gap above the wrist pin. (DUH!) He said I'm good to go there, .030" end gap and we're even good for 150hp worth of snow.

So, I said to myself "Self, (that's what I call myself when I talk to myself.) Self, put Mr. Nasty cam back in, and let's see what we can make a 347 do. So it's back in, the X303 has about 12 tubes worth of grease on it and saranwrapped, with matching numbered grease covered roller lifters.

Heading out now to degree Mr. Nasty in. Now all I need are some rockers, and it's GAME ON! :D

Re: "Temporary" engine
 

Mr. Nasty is degreed in, a whole .7* off. Shucks. :D

Valve clearance is:
1.6 Rockers
.215 Exh.
.143 Int.

1.7 Rockers
.177 Exh
.105 Int.

Now the cam is ground for 1.7 rockers (Cam Motion has it right on the spec sheet), but I'm not sure which ones to go with here. Is the extra lift worth it? I've been told that .100 is enough clearance on the intakes, but .105 seems awfully close to me at 7500 RPM.

What do you guys think?

Re: "Temporary" engine
 

.105 on the intake should be fine. Just make sure you have your stuff setup right. Where did you install the cam? You could back it up a couple few degrees and gain p~v on the intake, but you will lose a little on the exhaust.

Re: "Temporary" engine
 

I installed the cam straight up at 0*, centerline is ground at 108.5 and it's actually at 107.8

I thought about the 4* retard/advance thing, but wasn't sure which way to go, if any, so I left it alone. Still easy enough to change, don't have the front cover on yet.

Re: "Temporary" engine
 

Depending on how much compression you have, I'd tell you to advance that thing, but youre kinda out of room on the intake side. In which case I'd just leave it alone.
