OK new plan. I bought a 77 blazer with a 400 that I will transplant to my nova! It shows 68000 miles but Im sure its been turned over. The engine has steady vacuum of 18 in. and does not smoke. Hopefully the bearings, rings, crank and cylinder walls are in that good of conition of the 130000 mile 350(before it spun the bearing)
My plan is a set of throw in a set vortec heads and my 224* cam on the short block with new oil, pump water pump, and gasket set. Im just hoping the bearings and rings are ok for farther use (atleast need to get me by until I get my other 400 done)
I have heard that 400s wear more beocuse of the short rod? can anyone second that?

Try giving No. 1 Performance in Salt Lake a call.. 973-6411. They're on 17th S. & Redwood-- west side of street. I recently checked prices for my older 350-- a reconditioned .010 under crank was only about $115, and the complete bearing and gasket set was about $100. A decent quality aftermarket crank is about $225.

Let us know how It turns out...
BTW: If you buy a rebuild kit, (cheaper than single gaskets & parts) the bearings are all in there..
You can rent a Cam Bearing tool..Auto zombie..cost of the tool when you walk out the door..refunded when you bring it back unmolested..$0..

|Warrant||hmmm, I do understand, But Cleaned/tanked as in acid dipped? Or is tanked and acid dipped or what ever they do two different things? If not then I got to get new cam bearings correct? which is more $$ for labor and the part! ahh!|

Call down to some machine shops down in the City. You may get some better prices for the cleaning and checking.
You are only about 30 min from NSLC, and I KNOW there are shops in WestValley, Sandy, & Midvale that are reasonalbly priced.
Those small town places have their cutomers by the 'nads and they know it. Go somewhere there is competion and you may get better deals.
On a good note---I know there is a real good person around Roy. My Brother and I were taking both of his cars to the Cache Valley show in Logan in 2000.
(blown 350 46 Ford Coupe, Chopped----Restored 66 396 4spd ElCamino)
The 46 alternator bracket broke (custom) and disabled the car on the freeway. Some guy that was on his way to the show pulled up behind us, and removed the broken part--went to his shop and made a new one--came back and installed it (90 minutes) ON A SUNDAY, and would not accept any payment. Wish I could remember his name. He even showed up at the show to make sure the part was gonna be okay.--That bracket is STILL on the car to this day.

I think your missing the point here..
To have it inspected and tanked / Cleaned will / Should cost less than $100 (check with your local shops) This will eliminate the bad from the good AND insure it is clean when you put it back together..
What if you have Babbitt built up in the oil gallery's just reassembling it? your not going to get 500 miles much less 5000 miles before the engine starts to wear out..
Again, It's up to you..Whatever you feel comfortable with..
I did it that way a few times 30 + years ago myself ..since I go the other route and pay less in towing insurance..

AHHHH!! ok never-mind that plan...I will use my block that spun the bearing, reuse all the pistons with new rings. take the spun rod, and press it off the piston, weigh it and match it to another good condition stock rod that I have and repress the piston back on. And use a honing stone to get a god seal. Use a beautiful standard 350 crank that I now got. and install with new bearings all around. and go up from their with the rest of the parts from the engine, new gaskets etc.
The only thing is that I hope the ridge is still small to get past, and that the cylinder walls are ok(heat and lack of oil) if their good, Im confident it will work.

|Classix_Lover||Warrant... don't ignore what doc is telling you. You CANNOT take shortcuts when your dealing with engine related components. This reminded me of some kid in my class when discussing something as critical as bearing clearances and how it "doesn't matter" if you're off a little bit on your micrometer readings, etc. I couldn't help but laugh. Do what he's suggesting to you and yes, it's going to take a chunk out of your wallet most likely but it's better if it's going to save you from having major headaches later on by doing things right the first time. Imo, he's being really patient with you so take that into account. Other members here would just blow you off if you constantly ignore their advice. My 2 cents.|

Well if it was me without knowing the history of the blocks, except both had burned up crankshafts... I would never mix and match stuff into a block I suspected to be Kewl..without a shop inspection and tank/Cleaning..
BTW: What makes you think the Pistons , and rings are gonna fit in a different block, ?? as you said yours was bored max..Need to mic those..
Call me an alarmist..But it the worst feeling in the world to watch water pour out the plug holes the first time you fill the radiator..or fill the pan..Or after initial break in RPM you back it down to idle only to hear "Knock, Knock, Knock.." that gets louder as it runs more..
I'd pass on the vortecs and better spend the money on the shop costs .. If it were me..The heads will add nothing to the performance of the car if it starts barfing rods and spinning mains or has a big AZZED crack in 3 cylinder walls..into the water jacket..
Another way to look at it, assume the block and lower end are the foundation to your home..and you say, I'm gonna scrimp on that..and add KEWL looking doors and windows, Hot tub, hobby room with slate bed pool table..water bed, and so forth..Then a mild wind comes along and blows it over because the PLATFORM can't support the weight and stress of wind loading..you have a Pile of NEAT looking junk..
But then again..That's just me..
It's Your project, your budget, your labor..Do with it as you will..
Post back and let us know how it turns out

ok...here's the deal, I can get a used/good conditon crankshaft for both engines for $50. I think im going to go ahead and use the newer '87 block (becouse it looks like it has just been recently machined(although somthing happened with the crank)) and dissemble it(leave the rods and pistons mated together and clean them real well), Use a honing stone on the cylinders, reinstal everything that I had owned with new rings, bearings, and gaskets etc.
The reason I dont want to use the spun bearing engine, is becouse of the ridge and would probaly need to get it bored, , the and 2 rods are most likey need resizing(more cost and means I would have to get pistons pressed off and back onto the rods) $$$ and the cylinders...I just dont want to get into that.
But Im not familier with with these newer blocks. Can everything be swapped from my 1975 block to the 1987? Oil pump? Fuel pump? it doesnt have a flexplate, can I use my old flexplate on the new 350, or will it throw it out of balence? Also since it can use a OE roller cam, should I take advantage of that? What cam do I look for? Are they alot of $$$. I think I could get some good condition roller lifters out of a junk yard. and I might as well score some vortecs and do a budget rebuild on those???
What do you think?
|10-19-2006 10:55 PM|
It really not easy to say without inspecting either..especially over the internet..That's like me asking you, : Should I go with the Tat I have on on my right arm as is...or have it modified..Something from the equation is missing..
A 100,000 mile block can be better than a 1000 mile block..depending on what it looks like..It's history, and inspection..(That new block could have a Wall Crack in it..) That's why the tank and inspection to be safe..
As far as the reamers , If the ridge is not too sever, yes, they are very effective..They take time and patients to get it right..AND..If your reusing the rings and/or pistons..DO it before you pull them out .. not after..you could crack a ring or piston on the way out..
The key to any successful rebuild is Clean ,Clean, Clean, Straight and Smooth..
I know your on a tight budget..this , I think is the easiest way out for you..
|10-19-2006 08:43 PM|
Hmmmm...is .060 over the max for a 350? Couse if it is...I would think it would be a waste of time to rebuild that one(couse if somthing happens and I put money in it...I think I can use the block with a new hone and good clean...
Is it a bad idea to just hone my 100,000 mile block, can I get my pistons with new rings past the ridge? Are Ridge reamers effective???
Ahh idk what to do!!!
|10-19-2006 07:09 PM|
Well..Same movie..different channel..
Yes, It is a good idea to combine all the GOOD parts and make one engine..
HOWEVER , something made the #2 block barf the lower end also..So the block will most likely be contaminated..To do it correctly AND only once..
Do whatever machining you will to the block..when ready to reassemble..take it, and ALL the heads to the shop, have them hot tanked, and inspected for useful life..and level surfaces..(this is about the cheapest you'll get off in a shop, unless you know the guy well..)
WHEN you get them Back..
Pressure wash it, take your time and get it squeaky clean..Then air dry And wipe down important surfaces with light oil..Paint or whatever you want to do at this point, and install all your GOOD parts, And new gaskets..(get a set of core plugs..just cuz...)
Take your time, do it right...and it will do right by you..

Hey! thanks a ton smitty, I live on Joni dr. (near the end of antelope) I have a engine hoist and most all other things to build anything welders, air, etc (not a lift). (My dad is a building op a 37 chevy and a my brother a 65 rambler.
I think I have a plan, I'll use the older '75 block I have now and remove everything...clean it...and get ride of the ridge and get a new hone in it. The thing is I dont have a ridge reamer or a honeing stone... and I found a new crank for $50...reuse my rods and pistons with new rings...
and use all my other parts I already have.
