Buinicorn the 1964 Skylark wagon sleeper

[SuperBuickGuy]

Notes for myself:
317 heads 71.6 cc
243 heads 65 cc

need head bolts
Fel Pro makes a .048 MLS gasket (stock is .054)

Use LS7 lifters
*note, I am concerned about the stock lifters - so this a footnote to why rebuild

IF I can save the 317 heads with new seals and basic clean up, if not $500 for remans
ARP bolts are $75
head gaskets are 65/ea
bearings/rings are 376 for Hastings or comparable
LS7 lifters are $170
New pushrods
I'm sure machine work will be $500
rebuilt or new rockers $170

budget then is $1300 in addition to what I already bought worse case is 2k.

Did you roll the cam to see if the center journals were straight? Sucks that the enngine needs rebuilding..

How much for:
blower/turbo pistons?
better valve springs for blower/turbo applications?

See - I can help with this part!

[SuperBuickGuy]

I already have the springs
the pistons are fine for the boost levels I'm playing at

so helpful, I may even have the turbo necessary

[SuperBuickGuy]

good news, talked to my local machinist and he's "replace the bearings and run it"...much cheaper,

[SuperBuickGuy]

wrinkle finish

timing gear off


and here we go, disassembly

only interesting thing, the push rods were rattling against the heads

all in all, other then that wonderful ARCO fuel look, it looks really good


the lifters were worn, so changing these is a good thing


the bearings look new


a lot of carbon, but still no ridge, no gunk in the oil passages


mains look as good as the rods


and bagged for its trip for a clean and new cam bearings


both halves of the mains

crank looks great



in other news... the transmission guy said pull the filter and look to see if there's crap.... notice anything missing?


and the plug is broken


I'm not sure if I'm mad, I'm seriously considering buying the parts and rebuilding it.... why not?


the clue was the leaky pan - when I got it off there was no sealant, so it's been off

My face was wrinkle finished in the last few years. Seems to be holding up well even after repeated washings.

this is giving me wrinkles... actually parts total is roughly 1200* - I got a deal on heads (someone had them done then sold them on Craigslist), all I have left in parts to purchase is push rods - upgrade is thicker wall, so I'll thicker wall it.

*657 for rockers, lifters, trays, bearings, rings
*225 for gaskets and ARP head bolts
*300 for the heads.

machine work TBD, but at this point it's cleaning plus beat in the cam bearings.

Are the rod and main bolts TTY as well?

Are the rod and main bolts TTY as well?

oh lord, you like drama. I don't think they are... but know there is a small corner of the internet reserved for that fight - bring a snorkel, there is a lot of blood flowing there... of course, my bolts are second design ..... the issue is there is bolt stretch about 6800 rpm. I don't live there, my lifters don't live there....

"up to 3x"... in other words, as many times as you wish - those bolts have a captive sleeve on them and are a bit of a pain to replace. And now you see the genesis of that blood-letting.

[Deaf Bob]

Why tty better? You torque them to a hair before fail?

[SuperBuickGuy]

All bolts stretch, GM likes them because it allows aluminum on steel (different expansion rates) while maintaining the same clamping force... that said, we've used reuseable bolts on MLS gaskets for decades... so I'm not sure I understand it well enough to explain or even form an opinion (thus the knuckle-drag response)

bought rebuilt 317 heads today - $300. Anyone wonders why I love GM stuff... yeah, $300 for great flowing, aluminum heads and I still have my useable 317 heads that I could get a couple dollars back by selling.....

[SuperBuickGuy]

I'm supposed to get the block back tomorrow, and have most of the parts (except the heads, they're in Portland) to assemble it
in the mean time, time to clear a bench
fix the wiring harness (with a new one)


and the new one in place

and assembled (pan isn't tightened but at least it has a seal there now (rubber)
