I wouldn't mess with it. Someone has been in there, the cam valley is super clean. Maybe look at get another cam with more high performance. Great find. You really lucked out. Once you saw the high performance fuel pump and intake manifold, you really trusted your instincts. Way to go....
@@twolousgarage6054 Comp Cams has an interesting profile for the Buick v8s. # 96-210-4, an xtreme energy cam that doesn't have a lot of spread between advertised and .050s duration. Heard it run in a Buick 400, didn't have a radical idle. A little hotter than the Stage 2 stock cam.
A customer left two Buick 455's at his body shop. One I'm pretty sure is out of a 70 Riviera and I believe it might be a stage one. Both motors have been sitting outside for a number of years, he said I could have both motors for free so if the 70 motors froze up it's no biggy being its free.
Nice find!! I'm about 30 min north of Scranton in Forest City. I have a 70 Skylark. Has the original 350. I'm looking to put a 455 in or possibly an LS if I can't find a nice 455.
Thanks for watching! It will be *cheapest* to swap in a buick 455 if you can find one. You will need to buy BBB frame pads (readily available used and aftermarket), but other than that your th350 will bolt up and survive behind a mild 455. you can get away with the 350 power steering setup, and maybe the radiator depending on what is in it now. aftermarket 455 throttle cable, but you can make the 350 one work. I have a good running 455 currently in a 69 Riv i would consider selling. also have a few LS's laying around.
There is no casting number to show a stage 1 head, both non stage 1 and stage 1 used the same head, you do have stage 1 heads by the valves but they are not factory stage 1s as the factory heads came with the valve unshrouded. Still a great find but you info is a little off. Also the pistons are stock replacement low compression pistons the stage 1 used more of a flat top type piston to get the higher compression advertised. It also appears the block has been filled for drag racing. the coolant transfer holes all seem to be filled.
Great insight here, I meant to say correct casting # for a 70 head. I did not notice the block fill. I intend to run it on the street, so will have to plumb an oil temp gauge and make sure it doesn’t get too hot. Thanks for your comment!
It looks like you have the deeper dished pistons which were lower compression, but that does not always deter horse power on the Buick engine. With the being said, of course higher compression is always going to boost horsepower, but it is not that noticeable difference in the 1970 verses the later model engine, like 1971 or even later.
pull the pan off check a couple of bearings if they are good regasket the whole thing krylon rebuild it and send it 500 plus pound feet is a neck breaker tire destroyer whithout a do u fŷ

Thanks! When I pull the timing cover, I’ll be able to learn more about the cam. I have a couple cams laying around

Casting numbers are the same, how they are machined is what makes them different, you have the good heads.
Love it!! Double springs indicate a healthy cam! I used dual Lunati springs on mine, with a 248*/.520" lift Poston GS105A cam.

You Scored big time!!!
Thats a good find. Those heads alone are probably worth as much or more then you paid for the whole engine.

@Two Lou's Garage what would you want for the 455? Could it be run as is or would it need a rebuild? What LS's do you have?
@@twolousgarage6054 how much for the 455? Which LS’s do you have laying around?

This is a smog block with an rv style cam and stage 1 heads.
Did Buick NOT make any 4 bolt main blocks? I have yet to see one. I'm sure one could be made by adding the splayed caps and line honing them.
Not any production. There is at least 1 experimental 4 bolt main that survived. It is displayed annually at the GS Nats in Bowling Green
There were 4 original blocks I believe. 2 were complete tunnel port experimental motors.
The vin nr is behind the engineblock about where you connect the transmission.
Thanks for watching! That is just the casting number on Buick big blocks. It’s a 70-71 date coded block
The id is on the pass front but not on a 70
Only problem is if they are speed pro forged pistons and they didn't deck the hell out of it then the pistons will be like 0.040 in the hole
Did you watch the video, not only are they dished, they are significantly recessed as well.
There should be a VIN number on the passenger side next to the timing cover
Correct for a 71+ up 455. on a 70, they are stamped on the head surface
Where is the oil pressure switch located on a 455 block and where is the oil sending unit located
Located on the front passenger side of the engine slightly above the oil pan. look near the oil filter.
@@twolousgarage6054 is that the oil sending unit or oil pressure switch
@@smith85ish both, depending on your application. Most 455 cars just had an idiot light.
