1963 Skylark.....455 engine swap

Recommended Posts

Tenant bought a pretty good '63 Special, post, w/clutch pedal, floor shift, no signs of being a conversion.  There is a 1971 455 engine available to him.   As I understand it, this is the first year for unleaded gasoline engines.  I know B-O-P shared a common bellhousing pattern, how about a Pontiac flywheel on a Buick engine.???  How about front springs.???

 

What is the degree of difficulty in this engine swap.???

You didn't mention collapsed front coil springs.

Actually Ed, the 455 (and 400 and 430) Buick big blocks weigh less than the small block chevy.  I'd be much more concerned about twisting the car in half than the weight on the front end, that is if you could ever get it to hook.  If I am not mistaken, those years of Skylarks are unibodies.  Careful where you cut for clearance.

 

The flywheels will not interchange, to answer the OP's initial question.  Anything can be made to work but at what cost.

Gents........most annoying thing to over come is the unibody...  I have done 2 of the '63 Tempest cars that had the ridiculous trans/axle set up.   Been long enuff now, 40 or more years, that I am foggy on the details.  Probably figger it out if it were my car.....but at 80plus, I have stopped volunteering to do work for others.!!!!!  I even had an aluminum front end for one of the Tempests, but wasnt the correct car.......it did find its way to the correct SD wagon.

 

I doubt he is serious after noticing he bought a full set of the tiniest tires I have ever seen.  This car has chromed headers (????) & motorcycle mufflers and '64 Ford pivoting bucket seats.......how many folks remember Fords pivoting buckets.????

 

Here is a pict. of my aluminum front end Catalina during the mid 2000s at Farmington NC.

'63 Special/Skylard would have had a V6 or the aluminum V8 ..... I suspect a big block would be a very tight fit in that car.

Degree of difficulty.........when finished you would have at least an "Associates Degree" in engine swaps.   Unlikely you are going to find a "How To" book on that swap.

I don't think they started "detuning" the engines until '73 (unleaded gas) but it may not have been a overnight change in the engines.

Your friend need to do a lot of research.
