My 350 Build. Will it work?


Recommended Posts

Now don't get discouraged.

 

A stroked 350 is a 4.030" bore (that is a 4" 350 bore 30 thousandths over) and it has a 3.75 stroke which is a 400ci crank but of course they also make aftermarket cranks with 350 journals.

 

Don't take me offensively or anything, I would like to see you stroke your engine since you either have bought or are planning on buying new internals. What exacltly have you already bought? It's not a bad idea to return them for stroker parts. The point is, you're buying all of these things anyway and there is virtually no price difference in the parts. You would probably have to get the machine shop to clearance the block for the larger stroke crank but that's no biggie. Just don't get overwhelmed. Do what you're comfortable with. Ask us whatever you're not sure about, we don't mind.

I have determined my Build. I'm not going to stroke it. I do want this to be a Toy, but not so much of a Toy that i don't feel comfortable driving it more than 20 Miles at a time. When i say Toy, I mean Sounding Good and able to pull me and a Passenger back in our seat, but not really to race. In fact, i was planning on Driving it 200 Miles after i break it in to show it to my National Guard Buddies. I already have Everything i need to build it. I'm using a Single Profile Cam. I have some 882 Heads right now, but i figure that i can always change the Heads to Aluminum after Christmas since you don't have to remove the Engine for that. Someone mentioned earlier that i should Replace my 600 CFM Carb and get something Bigger. I agree with that, but again, that's something that i can do with the engine still in the Truck. Let me Go ahead and give you all an Updated list of what i have right now.

"I have all parts EXCEPT the Rods Currently. The Rods are on their way already also."

 

its the little stuff that adds up...

 

parts not listed, hopefully you have but just didn,t list

 

all the engine gaskets

valve spring retainers & keepers

carb mounting bolts

carb linkage

oil pan with gasket

front cover

water pump

flex plate

harmonic damper

belt pullies

timing gear/chain set

cam button

lifters

dipstick with tube

t-stat and houseing

oil pump

oil pump drive shaft

oil pump pick-up

all the bolts/fasteners and SEALANTS

the freeze plug and oil passage plugs

ignition & distributor

ignition wires

spark plugs

engine bearings

assorted machine work and ballancing the rotating assembly

hoses & belts

motor mounts

pushrod guide plates & rocker studs(may not be on heads)

internal magnets, & windage screen (optional)

 

thats why I usually suggest buying a cheap replacement crate motor with a warrantee when power levels are to be low, its a good starting point that supplies many of those parts, and I don,t want to be a jerk, but how can you sellect the pushrods without checking the geometrys correct for the length needed?

yes, i do have all of that. I did get a new Oil Pump assembly. I have all of the Required gaskets and I Have a Double Roller Timing set. I'm reusing my Old Water pump since that was new on the last engine when the previous owner Screwed up what was supposed to be a Rebuild (He used the Wrong Size Pistons and Rings). The Carb and Manifold were on the old engine, so they already have all the needed hardware. I will need spark Plugs, and i'll probably put a New Cap, Rotor, and Wires on the Engine. My Springs Came with Retainers and Locks. The Cam was a Kit that came with the Tappets. I have the Cam Bearings, but i Need to get the Main and Rod Bearings. I think i'll get another Thermostat, but i'm not sure what Temp Rating i should use. I live in Mississippi, So it gets pretty hot in the Summer. The Transmission already has a Shift Kit and it's own Cooler.

 

The Engine that i'm using USED to be a Crate engine. It's a '72 and the Truck is a '86. The Original thing i was gonna do was Replace the Heads. It Smoked ALOT as you could imagine for having the Wrong Pistons and Rings. I thought it was the heads. When they came off, i saw that i was wrong. The Previous owner's Brother Told me that he was adjusting the Valves by cranking the Rockers down as far as they would go. He Said his Brother Ruined the Cam and Tappets and he had to help put in new ones so his brother wouldn't screw it up again.

 

After i realized the Engine was going to be a Rebuild, a buddy of mine suggested to me that i should give it some performance while the engine is down. I agreed. That's how I came to be building this the way that i am. I'm a Rookie, like the last person that attempted to Rebuild it, but i think i'm Smarter. Does that sound Conceited?

"but i think i'm Smarter. Does that sound Conceited?"

 

HELL no!, thats how you/ me and most guys learned this hobby, you either jump in with both feet (SINK OR SWIM, and learn the hard expensive way) or hang out with more experianced guys willing to teach you,the pitfalls and fine points, its really not too hard to assemble a really nice engine IF you do the RESEARCH before starting and FULLY understand what your doing...thats one reason I stress the engine build CD and links posted above are a very good referance, youll be far ahead doing the research and taking addvantage of the available resources

Since we're posting a million links, here's this one. A 350 with 90% efficiency AND 6500rpm, which you will not do either with this combination, gives you a little under 600cfm.

You mentioned that someone had the wrong pistons in the engine, how do the cylinder bores look?? I may be wrong but 60 over is about the upper limit for a SBC, if the cylinders are not good your sticking money in a bad block, not trying to be the bearer of bad news but trying to help you NOT make a expensive mistake.

Back in the days, I had a set of .060 over 12.5:1 TRW's, .510 solid cam, set of ported 882 heads on a 350. Every time I rebuilt it I just got another block that was 0.030 or 0.040 over an bored it to 0.060, freshened the heads and let her rip. I never had a problem. Nowadays they can sonic check the block for thickness before you start for a nominal fee. Here it's $25.

I found a Place that will Balance my Rotating assembly for $125. The Only problem is that it's 100 Miles away. It's not easy to find services like that in Mississippi. I asked about Knife edging my Crank and they told me that it wasn't a good idea with a Stock Crank. They said that they would have to add weight to it to compensate and i would be better off buying a High Performance Crankshaft that's already Knife Edged. I can live with that. I'm still waiting on the Rods to show up at my door, but it should be any day now.
