Engine rebuilders.

I'm far behind on my 442 restauration,and now I consider buying a rebuild complete 455.I will keep the original # matching 400 for a later rebuild.

I haven't but there are several accomplished engine builders on here that could build you what you are looking for. Check with Mark cutlassefi he has done a few.

I paid much less for my 455 to be built by Buddy Rice Machine Shop in Oklahoma City, OK. It was about $1,200. He bored it, trued the deck, re-finished the crank, completely redid the heads and assembled the short block for me. All I had to do was put the heads, intake, oil pan and accessories on.

I am getting confused here.

https://www.sandjengines.com/rebuilt...OLD-455LB/7906

$1670 for a long block?A rebuild set will cost me almost that alone.

Have I misunderstood something
A longblock is a completee engine,without intake +carb.,valve covers,oil pan,pulleys,waterpump,alt.,starter,ignition+probab ly something else,is this correct?

I pm'd you jankyrre.
PM received,I ll be back.

Thanks.

I think the thing to remember here is that a lot of these adds are very generic.
For example the first one lists $4996 for a 400hp 455 with 4.500" Siamesed bore block, really? That doesn't exist. Ask them if they can cough one up, if so there will be a line out front.
All seem to use cast pistons, as forged is listed seperately.

And S&J engines will give you a new timing belt on your rebuilt 455, really?

My point is whichever way you go, ask what machine work is included and what isn't. What parts are they using etc? What aren't they replacing? It's your money, you have a right to ask any question you want.
Again these sites can be misleading, especially when it comes to something not so mainstream, like a 40 year old Olds.

Hope this helps.

I also usually pay between $1400 and $1600 to have a short block refreshed----after all its only putting a rotating assembly in a block other than checking everything and minor machine work like honing the cylinders. Same guy has done mine for years but its looking like he is going to retire soon.....could create a problem

I would be very wary of such a claim for a 400hp 455 olds, better listen to CutlassEFI, in fact you should contact him to build your motor. Very few generic engine companies would I trust with my 5000 hard earned dollars. Stick with Olds people!

Long block 455

I purchased my engine August 2009 from S & J, cost with shipping was $2,320. They did say they were starting to have problems finding good blocks. Chris

Been awhile,but decided to check out my original engine.
Got it cleaned up and have taken some quick measurements.
Need advice on what to do with the cylinders.This engine have never been bored.All cyl.are stamped A which means std.bore.
There is a ridge,can bearly feel it with my fingernails.
If I put the pistons in upside down I have a 0,1mm(0,004inch) clearance between piston and cyl.wall.This is measured just below the ridge.
What would you guys have done?The guess the options are 1_to hone the ridge away,put in new rings or 2_bore,oversized piston etc.

A BTR build will be at least $9K.

I have a quote for $12K......

A $1200 rebuild was the going price, in 1988.

jankyrre, What year is your 442? the early (pre 68) 400,'s were great motors a post 68 is not worth rebuilding, it has been suggested that it was the worst motor GM every put into production, a very under square engine, Long stroke, small bore, N/G, IMO Find a 455 if you want to go!

My442 - most of my all roller rebuilds run about $8500.00, give or take. That's dynoed and tuned, carb to pan. Unless you're looking for something above 500hp 12K is ridiculous.

Just got one back from the guy that has done mine for years and is still talking about retiring.......rings, bearings, new timing chain, new oil pump, etc. + had a crack in 1 cylinder so I took him a different block which had to be bored .030, line bored, decked, and re-balanced rotating assembly. $2200. This motor ran 6.80 right off the bat........don't know how much HP that is.....Last refresh was a couple of years back and was $1400. Motor performance was about the same. Notice that he provided no hard parts-pistons, rods, crank, balancer, flexplate, etc.

Decided to freshing up the original engine,maybe buy an hotter later.

Have a question about the rod journals.

Are they marked the same way as the main journals.While the mains were from std.size to E,the rod bearings are all unmarked.
Can't find anything in the SM about this.
Are the min-Max diameters in the SM correct?

Using the untouched areas on the crank as ref.I can't measure any wear,so the plan is to order new ones in the same size as the old .
