I am trying to get involve into the lowrider movement. I have recently bought a 63 impala, 4 door, hard top, with out the middle bar between the front and back door... I have no idea what type of impala it is nor do I know what type of engine it has..        I have looked in several catalogs and have not found one that looks like mine.  

Its no use asking questions on this site, nobody is ever here.

Does it look like this?



Its just a regular 1963 Chevy Impala 4 door hardtop.  

The Impala You Are Describing Is Exactly what you said- Impala 4dr hardtop. Hardtop is a term to say there is no b-pillar on the vehicle. This Model is the top of the line four door in 1963 but was not available in ss trim. The engine can be 4 different choices. A straight 6 cyl would be a 230 cu in. A V8 with rectangular valve covers would be either a 283(most common) or a 327. If you have a small 2 barrel carb and single exhaust, it is most likely a 283. Most 327's came with a 4barrel carb and dual exhaust. Your next choice is a 409 and that is very doubtful. The valve covers would be a "w" shape. 327 and 409's had a badge on the fenders while the six cyl. and the 283 only had a decoritive crest  

Thanks for replying!! The only differance is that my impala does not have the bar in between the front and the back window. Is it a different model??  

The pictured vehicle is termed as a four door sedan, not a hardtop. A sedan will all ways have a permanant frame or structure around the window while a hardtop will have no permanant structure around the windows
